"Newly restored Roland CR-5000
Knobs have been cleaner though and the case has been cleaned and refinished to get rid of yellowing. The original switches have been replaced with linear & silent keyboard switches and 3D printed keycaps.
The new switches are awesome and will easily last 40 more years. The case is missing some screws but is sturdy. The case has a stain shown on the right side of the drum machine. Everything works on this drum machine and it’s ready for a new home. Thanks!"

Sonicware Ambient Ø Sample Manipulation Experiement - Speak Clearly....
video upload by ChrisLody
"I had a an hour or so free time this afternoon to do something experimental, messing with the Ambient 0's Noise layer for the purposes of sample manipulation.
I found the tape deck shown, a Genexxa CTR-96, in a charity shop recently and bought it immediately as it had a tape inside. That's always in 'insta-buy' scenario for me and it paid off. On the tape is the phrase you hear, 'You should speak clearly to get the best recognition accuracy, full stop'. The lady repeats this 3 time on the 3 getting slower and sounding more frustrated. There seem to be children making noise in the background so my best guess is she was a teacher and was trying out some 90s speech to text which wasn't working well (it didn't back then), but I'm not sure. The rest of the tape is full of unintelligible voices of children in the presumed classroom. The tape deck has multiple playback speeds so I used High in order to be able to record the whole phrase in the sample time allowed on the Amb0, then pitched it back down afterwards.
So that's sampled into the Amb0 and then I use it's LFOs to mostly control pitch. In hindsight I should have also routed the level and cutoff, maybe in the future. It can do some interesting things with the stepped LFO shapes to pitch as they contain sections that stop moving so the speech is still recognisable. Also the reverse delay is very good for glitching things as you can hear at the end."
Future Sound Systems Cric Patch Journal: Two Voice Paraphony
video upload by Matt Lowery
"With freshly tie-dyed hands, I demonstrate and explain a Cric patch that has been on my desk for almost two weeks. We'll use Rene 2 to sequence two channels of Cric, send the resulting audio through the Vongon Polyphase, and create a big granular cloud to sit behind that whole situation. It'll be fun, you'll see.
