TEHP (alpha)

THEP is a silly little thing. It is CHOMPI's TAPE firmware with one change: changing pitch no longer changes speed. In TAPE every pitch change is a tape speed change; in TEHP a pitch shifter does the pitch, and everything keeps its length and tempo.

• Keys: every note keeps the sample's length, whatever key you play.
• Pitch knob: changes the pitch of the samples, not their speed.
• Looper pitch: the loop keeps its tempo, so it stays in time while you pitch it in fifths and octaves.
• Overdubbing while pitched records what you hear: the new layer stays in tune with the loop.
• Still tape: scrubbing, starting and stopping the looper, reset, wow & flutter.

Shares TAPE's files: samples, options.json and presets.json, in /TAPE like the launcher's TAPE (or the card root). Tip: "Tape Slew On": false in options.json removes the tape intro when you press play.

Details and known limits: README.

Install: with the multi-firmware launcher v1.1 or later, send TEHP.bin to a free slot from https://ugrossek.github.io/CHOMPI/. On a stock card, put it in the card root as the only .bin.

Alpha: tested on one unit; expect rough edges. Feedback is very welcome.
