Drop a single-cycle wave form into the window to use it as an oscillator*.

- Adjust START and END points to find the right sound.

- Waveforms of 600 samples in length are tuned to C0 and can be pitched as required.

- Other sample lengths can be automatically tuned using the AUTO setting.

- Modulate the START and END points for timbre variation (in AUTO mode) and VIBRATO (in FREE mode).

- Includes a simple demo ensemble with a couple of snapshots, plus a few waveforms. More to follow as I use and build library :)

Also check out Adventure Kid for hundreds of 600-sample single-cycle waveforms... or make your own!

(PCM Oscillator Module was haphazardly cobbled together by Henry Bainbridge, some time in 2019).

* wild amounts of aliasing can occur, no idea how to solve that, but since I am using this mainly as a subtractive syth for basslines I am in no mad rush to resolve.

Thanks Nick! Haven't had time to look at TRK-01 properly yet, but love the concept of it. Yes go for it! I am new to modular stuff so I haven't really started to put together any interesting ensembles so it would be great to see some :) (BTW I am releasing version 1.1 soon with front-panel patching courtesy of Stephen Lemp's templates).

Ah, Henry, what a relief. Now we can talk... love your module here and the bass end is fab. Reminds me of Trk-01 but more fun. I shall probably work it into an ensemble one day if you don't mind!

Agreed, thanks Nick, and whoever deleted those rants :)

Can someone report this guy "oh ok" below? The first rant gets very offensive.
