Cwejman S1 MKII - Sync Overdrive Feedback Study

video upload by verstaerker

"due to popular demand i made another sound-exploration session with the Cwejman S1. This time about a sync-based patch.
It needs quite a bit of finetuning to find a good spot for sync sounds. But i was really surprised how aggressive the S1 can sound if it's combined with it's own overdrive and a touch of feedback.

Yes this session is a bit long... but i think it's worth watching the whole 8 mins if interested in the timbrechanges the S1 offers with small tweaks.

the only external effect added is the some delay/reverb with the Dynacord VRS-23"

Sending lofi fuzz and crackles into long delay and reverb with some granular sampling. The grains (at +2 octaves) create subtle trails as they feed into the reverb and delay.

I’m using the VCA Decay to adjust the keys from muffled plucks to longer chords.

The raw sounds of the GX are so interesting but I couldn’t resist exploring what happens when sending them into big effects.

To my ears it’s beautiful.

Playing keys at 1:00
Pitch bends at 2:45"
