LetterBeacon Posted October 7, 2009 Report Share Posted October 7, 2009 I want to build a Midibox CV for my modular synth and I'm slowly getting my head around all the (excellent) documentation on the ucapps site. I have a few questions still though:I'm going to be building the Midibox CV using the AOUT_NG module. It is my understanding that I take the 8 CV outs from the AOUT_NG and the 8 Gate outs from the Core module. On the Core module the 8 Gates come from J5 - are the remaining 2 pins for the Clock and the Start/ Stop? If not, where do I get the Clock and the Start/ Stop from?What's the amplitude of the Clock signal? Is it 0-10V?I'm assuming the Clock signal syncs with the midi clock that comes from my computer's sequencer - i.e. the tempo of the song in the computer's sequencer - is this correct?Thanks a lot!

TK. Posted October 7, 2009 Report Share Posted October 7, 2009 I'm going to be building the Midibox CV using the AOUT_NG module.

On the Core module the 8 Gates come from J5 - are the remaining 2 pins for the Clock and the Start/ Stop? If not, where do I get the Clock and the Start/ Stop from?J5 provides Ground, 5V and 8 digital outputs. These digital outputs (0V/5V) are the gates. The clock is available at J6:RC, and the start/stop signal at J6:SC of the core module.What's the amplitude of the Clock signal? Is it 0-10V?No, it's only 0V/5V - you could amplify it to 10V with a transistor circuit. This is also a nice protection against overvoltages - very important for a modular system.I'm assuming the Clock signal syncs with the midi clock that comes from my computer's sequencer - i.e. the tempo of the song in the computer's sequencer - is this correct?Yes, the 24 ppqn MIDI Clock will be output as a 1 mS trigger signal.Best Regards, Thorsten.

LetterBeacon Posted March 7, 2010 Author Report Share Posted March 7, 2010 If I want to attach a switch to turn the LED backlight of the LCD display on and off to save on power, is it just a case of inserting an on-off switch along the wire that feeds the anode on the backlight? Is it really that simple? Thanks for your help! Quote Link to comment Share on other sites More sharing options...
