midisynced analogue 8 step sequencer with atmel tiny2313

YouTube via stereoping
"DIY-Microcontrolled sequencer is driven by an electribe and sends gate/cv1/cv2 to diy analogue synth. Starting with forward, 16-th note. The gate switches on top have 3 states: gate, off and gate&glide. Setting to the latter causes the note to be oprtamentoed. With the glidetimepot, the porta-rate can be adjusted. In middle of video the mode is set to random, later to 8th-notes and even later laststep is set to 3."

avr stepsequencer - advance by note

"A feature i like most on analag sequencers is step-advancing by note, means the sequencer advances one step when it gets a note/trigger. This enables you to let it shuffle or make special rhytmic patterns."

avr sequencer - dark dungeon of gatetime

"Nice sequence with variations just by altering gatetime."

mc909 as hardwarecontroller for parametertweaking korg dw8000

YouTube via stereoping

"I made little converterbox with a Atmel tiny2313 which translates midi controllerdata of the mc909 into Midi-System Exclusive-Data to change parameters in a korg dw8000 in realtime. This way, the mc909 is misused as a hardwareprogrammer. Most DW8000 parameters are implemented, not all though. Video shows live-parametertweaking. The wizard also maps data of midichannel 7 onto channel 8 to overcome the problem that the mc909-tracks cannot send on other channel as the default. I also made a box for the Kawai K3m. See other videos."

MC909 used as hardwareprogrammer for Kawai K3m - realtime performance

"The Kawai K3 and the Korg DW8000 are lovely hybrid-synths. But they arequite shitty to program cause of their lack of knobs. I made a little box which houses a microcontroller running a little selfwritten software. The wizard translates standard-midicontrollers (sent from e.g. the mc909) into manufactor-specific system-exclusive-mididata to tweak synth-parameters in realtime. Video shows a little knobfiddling on the Kawai K3. You hear the K3, the mc909 is just the hardwareprogrammer for it. It's not a fake, It's just midi :)"

MC909 Mididata converter - how it works

"little, bad video of what the midiwizard does, which can be plugged between MC909 and DW8000 or K3m to tweak parameters in realtime on these cool underestimated synths."

bubblesound LFO

via bubblesound via muff's forum:

"Specs:
6 outputs: Square, Pulse, Sine, Triangle, Saw and a Shaped Sine.
Range: Low - 30 minutes-25hZ, High - 30 seconds-900hZ
1 1V/oct input
Sync In and Out
Triangle core
2 FM inputs, switchable between Linear and Expo
Pulse Width and Sine Shaper Modulation attenuated inputs
14HP wide

the Sine Shaper is a non-linear shaping circuit and you can view it in action here

sine shaper demo from bubblesound instruments on Vimeo.

I'll be posting longer videos and audio of it actually doing stuff shortly, but it's much easier to just see the Sine Shaper doing it's thing than trying to describe it.

the uLFO has just about everything in it we want from an LFO, but if we've missed something feel free to jump in. We're looking to deliver our first shipment of these around early July, maybe a little sooner if our panels get done faster. And the uLFO should retail for somewhere around $160-180."
