As someone who likes to do synthesis on the Octatrack, I sometimes get frustrated by the two-octave limit when working with single-cycle waveforms, so I’ve made a little tool to help. It’s called OctaCycle and you can use it for free in your web browser.

It works by resampling each waveform into a sample chain, spanning 7 octaves by default. Each slice corresponds to an octave which can be selected using STRT.

To use OctaCycle, just press Import…, navigate to a folder containing any number of wave files (e.g. the AKWF set), and click Save .zip. You can adjust the starting note and range to your liking, as well as the cents offset (±100). Additionally you can change how the resulting files are named. Note: Your samples are processed entirely in-browser, though your browser may use the word “upload” when you import them.

OctaCycle is currently in alpha. I’ve been using it but my testing is pretty limited, and bug reports are welcome.

Welcome @spnw

With scales ? 64 slices correspond to 5 octaves and 3 semitones…(61+3).
Simply cannot work with 7 octaves chromatically . I did some chromatic sample chains so I am pretty sure.

There is only one slice for each octave. You choose notes by transposing as usual, using slice locking as an octave selector.

Ah sorry I missunderstood. Maybe you could make clearer in og post ?

Sure, I’ve tweaked it a bit. Hope that helps.
