4ms Tapographic Delay (TAPO) is a multi-tap delay with a unique interface and functionality. A tap is a delay unit that delays the sound that constitutes a delay, and each tap has a different delay time. With TAPO, you can program taps with velocity to produce a variety of rhythms, organic textures, resonance sounds, weird harmonies, even from drones and simple percussive sequences. It evolves by being moved in real time, whether it is voltage or manual. The setting of tap timing and velocity is called tapography in TAPO.
  • Tap sensor with velocity sensitivity
  • Up to 32 taps can be generated, with delay time, amplitude, filter and panning assigned to each individual tap
  • Each tap has a low pass or resonant band pass filter
  • You can morph and transition between delay settings over a specified amount of time
  • Virtually two feedback structures with repeat and feedback
  • It has 6 banks that can store 4 presets, and can store and recall up to 24 delay settings.
  • Tapography sequencer that can select sequence mode from forward, random, random direction
  • Synchronize with an external clock and divide or multiply
  • Gate output synchronized with delay rhythm
  • Delay time up to 174 seconds
  • Sampling is 16-bit / 48kHz and internal processing is done in 32-bit floating point. Software latency is 1.3 ms
  • Mono input, stereo output (mono output is also possible)
  • Firmware is possible by audio input

Setting with TAP button

You can switch the tapography presets and change various settings with the 6 buttons on the top. To call the tapography from any of the 6 presets, simply press the button. To save, first press and hold the preset button for 1 second, then press it again when it flashes red. This completes the save. If you accidentally press and hold it, do not press the button again and wait. The save will be cancelled.

You can further change the settings with the TAP button. The setting item is VEL / BANK / PAN / MODE, and while pressing the corresponding button (BANK is the second from the left from the left) while pressing the selection item on the right (BANK B is the fourth from the left), the setting is completed. to change.
  • VEL: Sets the effect of velocity.
  • BANK: Recall a bank containing presets that will be the source of preset calls / save
  • BREAD:Change the panning settings. Set SUM / R for mono output. For RND, panning for each tap is set randomly. ALT has panning set alternately for each tap.
  • FASHION:Switch between normal EDIT mode and sequencer mode that can sequence tapography presets. In sequencer mode, pressing the TAP clock or TAP sensor advances the sequence to the next preset.

Firmware update

The TD ships with the latest firmware installed, but if new firmware is released can download it from.The firmware provided in this .wav file format will be loaded into the module after booting the TD in bootloader mode.The contents of the .wav file should be played without interruption, change, or volume changes.Always before starting the update, the contents and volume of the file will not change until the update is completed, such as disabling the EQ of the software that plays the file, turning off the sample time stretching, turning off the system notification sound of the computer, etc. Please set it properly.If the file playback is interrupted, the module will be incomplete and you will need to start over with the update procedure.Below are the update steps.

  • Turn off the system and disconnect all cables connected to the TD.
  • Connect a monaural cable (ideally a patch cable) from your computer, tablet, smartphone, etc. to the TD's Audio In jack.
  • Hold down the Repeat button and turn on the system. The Delete and Repeat LEDs flash red to indicate that the module is in bootloader mode.
  • You can set the input level with the Level knob.Basically, the knob starts at about 2:00 (70%).
  • Play the .wav file at maximum volume. You can check the input level with the LED button.
  • Adjust the Level knob so that the yellow LED is lit and the last two red LEDs are not lit.
  • If an error occurs during playback, such as the level being too high or too low, or changes being made to files or playback status, all LEDs will flash this case,
    • Return .wav file to the beginning
    • Press the Repeat button to put it in the update retry standby state.
    • Play the .wav file again
  • If the file plays correctly to the end and the update is successful, the module will boot with the new firmware.Perform the following calibration with each update.


By performing calibration work, the 0V position of all CV inputs is set as the center.Calibrate if you experience problems such as the knobs being misaligned or the knobs not reaching the maximum / minimum values ​​after a firmware update.

  • Turn off the system and disconnect all cables connected to the TD.
  • Hold down the Delete button and power on the system.
  • All LEDs will flash yellow to indicate successful calibration.
