rosch Posted May 28, 2010 Report Posted May 28, 2010 wow! can you switch audio with these? eg to make circuit bends sequenceable? Quote
lemonhorse Posted May 29, 2010 Author Report Posted May 29, 2010 (edited) can you switch audio with these? yes. it would be an interesting experiment. but i used the MBHP_4066 board just for MIDIfying a Yamaha VSS-200 yet (for interfacing the keyboard keys and the buttons). http://en.wikipedia.org/wiki/Yamaha_VSS-200 Edited May 29, 2010 by lemonhorse Quote
vcfool Posted May 29, 2010 Report Posted May 29, 2010 Great. Nice project! I have been using 4066 to trigger some of my bend devices. The 4066 controlled from analogue sources: Gates and Triggers from analogue synths or MIDI-CV converters. I'd be interested on building and trying one of this. Are you using a custom MIOS application to control the VSS-200? Quote

Are you using a custom MIOS application to control the VSS-200? i'm working on a MIDIBox VSS200 application (core8, asm): http://www.subfrequenz.net/visuals/albums/userpics/MIDIBox_VSS200_MBHP_V1_1.png http://www.subfrequenz.net/visuals/albums/userpics/MBVSS200CMOS4066BoardV11.png it's work in progress :-) Quote
widdly Posted June 8, 2010 Report Posted June 8, 2010 (edited) I don't know how these would go switching the negative cycle of audio signals. Normally when switching audio with a 4066, a DC bias is added to the input so the negative voltage is higher than the negative supply of the 4066. If you wanted to use larger audio signals like in a modular synth I'd try the DG211 chip instead. You would need a bipolar power supply though. Edited June 8, 2010 by widdly Quote
