Freeze Patch

Connect an audio input source and infinitely loop short audio samples (aka ‘freeze’) manually or automatically. Use four different modes to freeze sound. Connect a foot switch or freeze with the Aux button. Mix dry/wet audio to get the right blend. Transpose the frozen sound with the keyboard.

Version History
1.0 – Initial Release – July 23 2022


Connect a sound source or use the internal microphone. Connect a foot switch. Select a mode and play sounds with your external instrument. While sound is playing press foot switch or Aux button to freeze sound. Continue playing sound, then freeze a new sound. Play along with frozen sounds.

    Thanks Critter & Guitari for another awesome patch!
    I can’t really wrap my head around how threshold low and threshold peak work. Could you please elaborate on these two controls?

    a great freeze effect just like the EHX Freeze pedal (plus the transposing).
    Like in the Freeze pedal, the sample length is fixed. I think it would be very interesting to make it adjustable. And like Christian says, the threshold settings aren’t completely obvious. With guitar as sound source, I have set peak to 70% and low to 60%, just by trial and error, and without understanding what I’m tweaking here, but it seems to give the best results
