FAQ
What types of files can I load into my S-4?
The S-4 can read .wav and .flac file formats in 8, 16, 24 and 32 bit. When loaded, samples will be converted to stereo 48 kHz.
Can the S-4 record and store files locally?
Recordings made on the S-4 can be stored locally to the hard drive, and used for loading into TAPE or POLY or for transferring to a computer.
- Navigate to the TAPE device, and use [CTRL] + Save to save the current TAPE buffer.
- Navigate to MIX, and use [CTRL] + Rec Main to record the main output of the S-4. The recording can be stopped when pressing again.
Where are recorded files stored on the S-4?
When recording audio on the S-4 the files are stored in two different folders:
- SAMPLES/BOUNCES when saving the buffer from the TAPE device.
- SAMPLES/RECORDINGS when recording the main out from MIX.
Files are stored in 48 kHz 24-bit stereo .wav format. The TAPE buffer is automatically stored in the project file, and will not need to be saved manually in order for a project to load.
How do I transfer audio files from my computer to the S-4?
To transfer files to the S-4, USB Mass Storage mode needs to be enabled in the Config menu after connecting the S-4 to a computer via USB.
USB Mass Storage mode is enabled by pressing [CONFIG] -> SYSTEM -> USB MASS STORAGE.
Can I use a USB flash drive to load samples?
When inserting a USB flash drive into the S-4, a folder in the Sample Browser becomes available called USB DRIVE. The samples on the drive can be accessed from this folder.
The USB flash drive needs to be formatted to either exFAT or FAT32 in order for it to be used with the S-4. You can not copy the samples from the USB flash drive onto the S-4.
How do I delete projects or samples from the S-4?
To delete a project or sample from the S-4, navigate to the desired file and press [CLEAR]. A confirmation will appear before the file is deleted.
How many grains does the S-4 support?
The Mosaic device on the S-4 can use up to 128 grains per track.
Can I save BPM settings on imported samples?
If samples transferred onto the S-4 contain a number followed by “bpm” or “BPM”, the Tape device will automatically set the Tempo parameter to the specified BPM. Example:
“mysample_128bpm.wav”
How does audio over USB work?
The S-4 provides an USB audio interface with 10 in / 10 out channels for multitracking. The output is routed as follows:
Out 1/2: Stereo master
Out 3/4: Track 1
Out 5/6: Track 2
Out 7/8: Track 3
Out 9/10: Track 4.
Audio over USB currently works in these cases:
- When connecting the S-4 to a DAW and iPad
- Have been confirmed to work with Zoom H8
- A selection of small USB audio microphones and speakers
We are planning to expand support for other USB audio interfaces in a future update.
Can I bypass individual devices?
Devices can be bypassed by using the [CTRL] + Device Slot button combination. Navigate to and select BYPASS by continually pressing the Device button, turning the rotary encoder, or pressing the UP and DOWN arrows on the Action Buttons. Let go off [CTRL] or press SELECT to disable the device.
How do I clear parameter values?
To quickly revert a parameter back to its original state, hold [CLEAR] and press or turn an encoder. Holding [CLEAR] also gives the option to clear all modulation, parameters or device using the Action Buttons.
How does the POLY device respond to MIDI?
The POLY device can use up to 8 voices simultaneously. POLY does not receive pitch bend or aftertouch at the moment. The MIDI channel can be configured for each track in the Config menu.
Can I monitor a track using the headphone output before it goes to the master?
There is currently no way of cueing tracks on the S-4 before it is routed to the main output. A workaround for this, is to use the USB outputs to route and mix the tracks externally in a DAW.
Can I timestretch a sample without affecting the pitch?
To enable Keylock use [CTRL] + Keylock in the TAPE device. With Keylock enabled, adjusting the project Tempo or the Tempo parameter in the TAPE device, the pitch of the sample will not change.
What is the maximum length of loaded samples?
The S-4 supports samples of up to 6 minutes in length in either the TAPE or POLY device buffers per track.
Is MIDI CC implemented in the S-4?
All parameters on the S-4 are available to control using MIDI CC. The individual tracks correspond to the MIDI Channel set in [CONFIG] -> TRACK -> MIDI CHANNEL. By default the tracks receive MIDI on MIDI Channel 1, 2, 3 and 4.
See manual p. 120-124 for MIDI CC values.
Can I sync my other gear using MIDI?
The S-4 does not yet have MIDI sync as for V1.0.0, but is a highly prioritized feature that will arrive in a future update.
How does Ableton Link work?
The S-4 does not yet have Ableton Link v1.0.0, but will arrive in a future update.
Why is the S-4 not updating after transferring an update file?
The S-4 requires a .zip file for performing firmware updates. Please make sure not to unzip the downloaded file before transferring it to the S-4.
We frequently encounter issues with Safari automatically unpacking zip files post-download. To prevent this, please uncheck the box in Safari called:
“Open files after downloading” in - Settings -> General

FAQ
How do I perform a manual firmware update?
If your T-1 got bricked during a firmware update you will need to perform a manual firmware upload. Follow the instructions below to perform a manual firmware upload:
- Run from the menu bar of T-1 Config: “Tools” → “Download Firmware”
This will place a .zip in your download folder - And then “Tools” → “Upload Firmware”
Select the downloaded .zip in the pop-up dialog - The script will now upload firmware to your T-1, it takes about 2 minutes.
NOTE: If automatic port detection fails, follow the on screen instructions to manually enter the serial port.
macOS: It will be called something like “/dev/tty.usbmodemXXXXX”
Windows: It will be called something like “COMxx”, select the one with baudrate = 115200 or 460800
My T-1 is bricked and unresponsive. How do I fix this?
There are two known reasons for this behavior.
1. T-1 got bricked during a firmware update.
- To fix this you can flash the firmware manually.
2. One of your saved banks is corrupt, causing the T-1 to keep crashing upon startup.
- To fix this you can do a factory reset, which will erase all banks and settings
My T-1 keeps failing the firmware update process. What to do?
Make sure that you are following these steps before updating:
- You have the latest version of T-1 config installed.
- You have connected the T-1 directly to your computer without any usb-hubs.
- You have removed all MIDI cables from the T-1.
- You are not sending any MIDI including clock via the usb.
If the process keeps failing see “How do I perform a manual firmware update” to update to the latest version included in the T-1 Config tool.
My T-1 doesn’t load in T-1 Config. How do I solve this?
Check that your T-1 is appearing as a midi device in your DAW and is responsive when powered up. If this is the case here are some things you can try to make T-1 Config load:
- Make sure that you have the latest version of T-1 config installed.
- Perform a manual update to ensure your are running latest firmware.
- Reload the Config app by pressing “CMD+R”/”CTRL+R” or “View” → “Reload”.
- Unplug and replug T-1 directly to your computer ( avoiding any usb-hubs).
If any other external midi devices are connected, try to disconnect them and then go to 1. and 2.
- Try flipping the usb-c connector.
How do I start the T-1 in safe mode?
Follow the instructions below to boot your T-1 in safe mode:
- Hold [ CTRL ] while plugging in power to your T-1. You can release the button once the first track button LED is lit in orange.
- Your T-1 should now boot with an empty bank.
TIP: Banks are not automatically loaded in safe mode, so you can use this to check if you have a corrupt bank
How do I perform a factory reset?
On the T-1, a factory reset is done by erasing all banks and settings:
- Run from the menu bar of T-1 Config: “Tools” → “erase banks and settings”
- The script will now erase the file system on your T-1.
- After the process is completed the T-1 will reformat with the LEDs lit in orange. This can take up to 1 minute before the reformatting is completed.
Tip: If your T-1 crashes upon startup, it might be due to a corrupt bank. Use safe-mode to check if this is the case, and use factory reset to fix the issue
