15 min read
A hardware synth often uses separate connections for MIDI and audio, although some synths can carry both over USB. MIDI carries notes, controls and clock, while audio carries the sound you hear. This tutorial shows how to connect a hardware synth to a DAW in three common setups, including a complete Korg Minilogue XD example, then covers monitoring, clock sync and recording the finished part.

Audio, MIDI and USB do different jobs
The first thing to understand is that MIDI is not sound. It carries instructions such as notes, velocity, controller movements, program changes, tempo and transport messages. A recorded MIDI clip can play a hardware synth, but the clip contains no recording of that synth's output. Our explanation of what MIDI is and what it is used for covers the wider standard in more detail.
Audio is the actual sound made by the instrument. It leaves through analog outputs such as L/MONO and R, or through a digital audio connection when the synth supports one. Recording that signal creates an audio file that you can edit and mix without keeping the synth connected.
USB only describes the connection, not what travels through it. A USB port may carry MIDI, stereo audio, several audio channels or some combination of them. Check the specifications or manual for the words "USB audio" before expecting a single cable to record sound.
A quick check usually points to the right setup. Use USB-MIDI with separate audio cables when the manual lists USB MIDI but not USB audio. Use five-pin DIN when USB-MIDI is unavailable or causes problems, and use one-cable USB audio only when the manufacturer confirms that both audio and MIDI are supported.
USB MIDI only: use separate analog audio cables
Five-pin MIDI only: add a MIDI interface and analog audio
USB audio and MIDI: one cable may carry both signals
USB for data or updates: do not assume it handles performance MIDI
What you need before connecting anything
A common USB-MIDI setup with separate audio needs a data-capable USB cable, an audio interface and one or two quarter-inch audio cables. A mono synth needs one line input, while a stereo synth normally uses two. Connect your headphones or monitors to the audio interface so the DAW and synth share one monitoring path.
Match the cable to the synth's outputs. Unbalanced quarter-inch outputs such as those on the Minilogue XD normally use TS cables, while other instruments may offer balanced TRS outputs. Check the manual rather than choosing a cable from the connector shape alone.
Synths and drum machines normally send a line-level signal, so choose LINE on the interface. Do not select INST, Hi-Z or a microphone-only XLR input, and do not add phantom power because a synth output does not need it. The wrong input mode can add too much gain, cause distortion or give you poor level matching.
Start with the interface gain low and put the synth's master volume at a sensible middle-to-high setting. Play the loudest part you expect to record, then raise the interface gain while watching the DAW meter. Leave enough space below clipping for louder notes, resonance changes and effects.

Setup 1: USB-MIDI with separate audio cables
This is the most common way to connect a modern hardware synth to a DAW. USB carries MIDI between the synth and computer, while the synth's analog outputs feed the audio interface. The interface then carries the audio into the computer and sends your complete mix to the monitors or headphones.
Connect the synth's L/MONO output to one interface line input for mono recording. For stereo, connect L/MONO and R to two interface line inputs and select that input pair on a stereo DAW track. Make sure left and right use matching gain settings so the stereo image does not lean to one side.
Connect the synth to the computer with a data-capable USB cable, then connect the audio interface to the computer. Select the interface as the DAW's audio input and output device. Enable the synth's USB MIDI input and output ports, then create a MIDI track and an audio track.
Route the MIDI track to the synth's receive channel and route the audio track from the connected interface input or pair. Arm the MIDI track when you want to capture the keyboard performance. Arm the audio track when you are ready to record the actual sound.
Synth USB to computer: MIDI in both directions
Synth L/MONO or L/R to interface line inputs: audio
Interface USB to computer: audio input and monitoring
Interface outputs to headphones or monitors: complete mix
Setup 2: Five-pin MIDI DIN with separate audio
Five-pin DIN does the same performance-control job as USB-MIDI, but it requires a MIDI interface. Connect the interface's MIDI OUT to the synth's MIDI IN when the DAW only needs to sequence the instrument. Remember that OUT always connects to IN, rather than joining ports with matching labels.
Add a second cable from the synth's MIDI OUT to the interface's MIDI IN when you want to record its keyboard, wheels or knob movements. The analog audio connections do not change. Five-pin MIDI carries instructions, so the synth's output still needs one or two line inputs on the audio interface.
DIN is useful for older instruments, computers with limited USB ports and setups where a manufacturer's USB driver causes trouble. It can also keep several instruments connected to one interface, since a MIDI port provides 16 logical channels. Each device or multitimbral part must listen on the intended channel.
Avoid running USB-MIDI and DIN MIDI to the same synth unless you have a clear reason. Two active routes can send every note twice or create a feedback loop. Disable unused MIDI Thru, Soft Thru and clock routes if the setup produces stuck notes or a stream of unwanted messages.
One MIDI cable: DAW sequences the synth
Two MIDI cables: DAW sequences the synth and records its controls
One audio cable: mono recording from L/MONO
Two audio cables: stereo recording from L and R
Setup 3: MIDI and audio over one USB cable
A true USB-audio synth can send MIDI and digital audio through one data cable. The Roland SH-4d is a useful example because its USB-C port handles both. Its physical connector looks like an ordinary USB port, but Roland's specifications confirm the audio feature.
With firmware 2.00, the SH-4d offers GENERIC and VENDOR driver modes. GENERIC provides class-compliant stereo USB operation, while VENDOR uses Roland's dedicated computer driver and exposes 12 recording channels. Change `USB Driver` in SYSTEM SETTINGS and restart the SH-4d after changing modes.
Select the synth as the DAW's audio input device and enable its MIDI ports. With the dedicated driver, the DAW can receive the main mix and separate parts, which is helpful because the SH-4d has four synth parts and a rhythm part but one physical stereo output pair. Generic mode provides the simpler stereo route.
This setup has one practical limit. Many DAWs use one audio device at a time, so selecting the synth may replace the interface connected to your monitors and microphones. On macOS, an Aggregate Device can combine devices, but using the normal interface and the synth's analog outputs is often easier.
If the SH-4d is missing, check its firmware, driver mode, operating-system driver and USB cable. A charge-only cable cannot carry its audio or MIDI data. Roland's SH-4d Desktop Synthesizer Overview shows the instrument and its multitimbral design, which explains why its separate USB channels are useful.
GENERIC mode: class-compliant stereo USB audio
VENDOR mode: dedicated driver and discrete channels
Windows: use the correct Roland driver when required
macOS: install the Vendor driver or use an Aggregate Device when needed

Configure the synth and DAW
Every DAW needs the same basic routing even when its menus use different names. If you are still choosing one, see our post on which DAW is the best. Select the correct audio device, enable the MIDI ports, choose a matching MIDI channel and create a route that sends MIDI out while bringing audio back. Keep the MIDI and audio separate until you are ready to record the final sound.
The MIDI channel must match at both ends. Channel 1 is an easy starting point, but any channel from 1 to 16 works when both the track and synth use it. If the meters show incoming MIDI but the synth remains silent, check the output port, channel and monitoring state before changing cables.
A combined external-instrument device can place MIDI routing, returned audio and latency control on one channel. Separate MIDI and audio tracks are just as valid and can be easier to understand at first. In either case, name the tracks after the synth and save the setup as a project template once it works.
Ableton Live
Ableton Live's External Instrument device sends MIDI to a selected port and channel while returning audio from the connected interface inputs. Set `MIDI To`, choose the synth's channel and select the input or stereo pair under `Audio From`. Its Hardware Latency control can correct a late return from the synth.
You can also use one MIDI track and one audio track with `Audio From` set to `Ext. In`. When printing the part, record the External Instrument track onto another audio track in real time. Use Pre FX if you want a clean recording without Live's channel effects.
Logic Pro
Logic Pro provides an External Instrument plug-in for working with external MIDI gear. Choose the port that reaches the synth and the interface input receiving its output.
Hardware parts must be recorded or bounced in real time because the DAW has to wait for the physical instrument. You can instead use separate External MIDI and audio tracks if you prefer to see the two signals independently.
FL Studio
In FL Studio, use a MIDI Out channel to send notes to the hardware synth. Bring the synth's audio back into the DAW through the audio interface when you are ready to record it.
Turn on `Send master sync` only when the synth should receive tempo and transport information. Image-Line's MIDI Out instructions explain the available MIDI Out controls and settings.
REAPER
In REAPER, create a track for the MIDI performance and route it to the hardware synth. Set that track to send MIDI to the synth on the matching channel. Create another track with the connected mono or stereo audio input for the synth's return.
REAPER can record MIDI and the audio return on separate tracks at the same time. Keep monitoring deliberate, because hearing the interface's direct signal and the monitored DAW track together produces a delayed double. Our introduction to REAPER's audio recording modes covers the recording side in more detail.
Korg Minilogue XD: a complete working example
The Korg Minilogue XD uses USB for MIDI, not audio. Its rear panel has a USB-B port, five-pin MIDI IN and OUT, and separate unbalanced OUTPUT L/MONO and R jacks. This is exactly the kind of synth that needs USB-MIDI plus separate analog audio. If you are still deciding which Korg to buy, our comparison of the Minilogue and Minilogue XD looks at the differences in sound, filters, effects and price.
With everything turned off, connect OUTPUT L/MONO and R to two interface line inputs using quarter-inch TS cables. Connect USB-B from the synth to the computer and connect the interface to the computer. Plug your headphones or monitors into the interface, then turn on the equipment and set the interface inputs to LINE.
In the DAW, choose the audio interface as the audio input and output device. Enable the Minilogue XD USB MIDI input and output, then create a MIDI track routed to the synth and a stereo audio track using the two interface inputs. For mono recording, use only OUTPUT L/MONO and a mono DAW input.
Set the Minilogue XD `MIDI Ch` from 1 to 16 and choose the same channel on the DAW track. In GLOBAL EDIT, set `MIDI Route` to `USB` when USB is the only MIDI route, or use `USB+MIDI` when both connector types are needed. If communication fails, this is one of the first settings to check.
Set `Local SW` to `Off` when the DAW sends your incoming performance back to the synth. Otherwise, each key can reach the sound engine directly and again through the DAW, producing doubled attacks and reducing the available polyphony. You can keep Local on instead, but only if MIDI input monitoring or echo is disabled in the DAW.
For DAW tempo over USB, set `Clock Source` to `Auto (USB)` and enable clock output for the Minilogue XD port in the DAW. Use `Auto (MIDI)` for a DIN connection. Set `En Rx Transport` on when the DAW should start and stop the internal sequencer, or leave it off when you only want tempo-synced modulation and effects.
As of November 2, 2026, Korg lists system firmware 2.10 and Windows KORG USB-MIDI Driver 1.15 r63e on the Minilogue XD download page. Once the connection works, save a DAW template and note the program number used by the project. If you want finished sounds for this synth, our Motions and Isenveil bundle provides patches made for the Minilogue XD.
Korg's minilogue xd Tutorial/How-to 1 introduces the instrument's controls and signal path. It is useful after the connection is working and you want to understand what the recorded MIDI is controlling.
Korg's introductory Minilogue XD tutorial explains the instrument's main controls after the DAW connection is ready.
Monitoring, latency and MIDI clock
Choose either direct monitoring or software monitoring for the live audio path. Direct monitoring sends the interface input straight to its outputs with near-zero latency. Turn DAW monitoring off on that audio track, or you will hear both the direct sound and a delayed copy.
Software monitoring sends the synth through the DAW, so you can hear plug-ins and DAW effects while playing. This route includes input, buffer, processing and output delay. Use a smaller buffer while playing, then raise it if the project starts to crackle or drop out.
External instruments can also land late on the timeline. Record a short percussive note against the grid and measure the offset instead of assuming it is zero. Correct the result with the DAW's hardware-latency setting, MIDI track delay or recording-offset control, depending on whether the problem affects monitoring or the recorded file.
For synchronization, make one device the clock master. The simplest choice is usually the DAW, with clock output enabled only for the synth that should follow it. Set the instrument to Auto, External or the exact USB/DIN clock option named in its manual.
Clock can keep arpeggiators, sequencers, LFOs and tempo-based effects moving at the project tempo. Transport reception is a separate choice on some instruments, including the Minilogue XD. MIDI clock does not guarantee sample-accurate audio placement, so timing compensation may still be needed.
Record MIDI first, then print the audio
Recording MIDI first keeps the performance editable. You can correct notes, velocities and timing, then send the edited clip back to the hardware synth. You can also change its patch or adjust the front-panel controls before committing the result.
Keep the MIDI track and audio return active while shaping the part, but avoid recording two monitored audio paths. When the sound is ready, arm a new audio track, check the loudest passage and record the hardware output in real time. Hardware synth parts cannot normally be rendered faster than real time because the physical instrument must play them.
Record stereo when the patch uses stereo effects, panning or separate left and right movement. Use L/MONO when the patch is effectively mono, interface inputs are limited or you want to position the sound later in the mix. A stereo track made from only one connected output will often give you silence on one side.
Save enough information to recreate the part before disconnecting the synth. Write down the instrument name, program number, MIDI channel and any important global setting in the project notes. Save the patch on the synth when you edited it, and consider a SysEx backup when the instrument supports one. On the Minilogue XD, our post on using the Sound Librarian app shows how to export your presets to the computer as a backup.

Which setup should you use, and what can go wrong?
USB-MIDI with separate audio is the best default for most current hardware synths. It suits players who want simple MIDI editing while keeping an existing audio interface as the center of the studio. Skip it in favor of DIN when the USB driver is unreliable, ports are limited or electrical noise appears only with the USB connection.
DIN MIDI is the better choice for older gear and stable multi-synth rigs, provided your interface has MIDI ports. One-cable USB audio suits instruments with confirmed USB audio support, especially when they provide useful separate channels. Skip that method when selecting the synth would disconnect the interface already handling your monitors and microphones.
A two-input interface is enough for one stereo synth, but it leaves no spare input for a microphone or second instrument. Choose more line inputs if several machines must remain connected. A MIDI DIN port is also worth having when you own older gear or want a backup route that does not depend on a synth's USB driver.
Troubleshoot the signal in order rather than changing several settings at once. Check MIDI input, MIDI return to the synth, the synth's output, the interface meter, the DAW audio meter and finally the monitor path. That sequence shows exactly where the signal stops.
MIDI appears but there is no sound: add the synth's analog audio return or verified USB-audio input
Minilogue XD appears over USB but will not record audio: this is expected because its USB port is MIDI-only
Every note sounds twice: disable Local Control or disable the DAW's MIDI echo
The sound is phasey: turn off either direct monitoring or DAW audio monitoring
Only one side is audible: choose a mono track for L/MONO or connect both outputs to a stereo pair
The USB synth is missing: check the data cable, driver mode, firmware and DAW restart
USB adds noise: try another port and cable, remove hubs, use a common power outlet and compare DIN MIDI
Recorded audio is late: measure a short test note and adjust hardware latency, track delay or recording offset
Clock drifts or loops: use one clock master and disable duplicate Sync input, output and MIDI Thru routes
Notes get stuck: remove duplicate MIDI paths and unnecessary bidirectional routing
Our verdict
USB-MIDI with analog audio is the safest setup for most synths, while true USB audio is useful when the instrument and your DAW support it properly.
Pros
Editable MIDI before recording audio
Reliable monitoring through one interface
Works with old and new synths
Clear options for mono or stereo
Cons
USB does not always carry audio
External hardware adds some latency
Stereo synths use two interface inputs
Multi-device USB audio can be awkward
What is the best way to connect a hardware synth to a DAW?
For most musicians, USB-MIDI with separate analog audio is the most dependable choice. It keeps your normal interface in charge of monitoring while giving you editable MIDI and a clean route for the synth's sound. The Korg Minilogue XD is a clear example of this setup.
Use five-pin DIN when USB is unavailable, noisy or troublesome, and use one-cable USB audio only after checking the instrument's specifications and driver requirements. Whichever route you choose, keep one MIDI path, one monitored audio path and one clock master. Record the MIDI first, then print the final audio in real time once the performance and patch are ready.

Frequently Asked Questions
Do I need an audio interface to connect a hardware synth to a DAW?
Usually, yes. You need an audio interface when the synth sends sound through analog outputs, but a synth with confirmed USB audio can connect directly to the computer.
Does USB carry audio from a hardware synthesizer, or only MIDI?
It depends on the instrument. A USB port may carry MIDI only, audio and MIDI together, or data for updates, so check the specifications for the exact words "USB audio."
Can I connect a synthesizer directly to a computer without an audio interface?
Yes, if the synth provides USB audio. A MIDI-only USB connection can record notes and controller data, but it cannot record the synth's sound.
How do I record MIDI and audio from a hardware synth at the same time?
Create a MIDI track routed to the synth and an audio track receiving its analog or USB audio return. Arm both tracks, check monitoring and record the performance in real time.
Should I use USB-MIDI or five-pin DIN MIDI?
Use USB-MIDI for the simplest direct computer connection. Choose DIN for older instruments, dependable multi-synth wiring or when USB drivers, noise or duplicate routes cause problems.
Why do I hear doubled notes through my DAW?
The synth is probably playing each note locally and receiving the same note back from the DAW. Turn Local Control off or disable the DAW's MIDI input monitoring and echo.
How do I synchronize a hardware synth to the DAW tempo?
Set the DAW as the only clock master and enable MIDI clock for the synth's output port. Set the synth to its external, Auto USB or Auto MIDI clock mode, and enable transport reception only when needed.
Should I record a stereo synth in stereo or use L/MONO?
Record in stereo when the patch uses stereo effects, panning or width. Use L/MONO for a mono sound, when interface inputs are limited or when you want to place the signal later in the mix.
