Hi,

I'm going to start on this DIY synth shortly when the rest of the parts have arrived. I have a question about the voltages to some of the pots and where the voltages are taken from. I realise the kit is intended for experianced electronics people but after having made a few x0xb0x kits and Klee sequencer I'm not too bad with a soldering iron, just not that good with power to certain things :) The Doepfer synth kits instructions are pretty good for a beginner I feel, just need a few more instructions on voltages for people like me :D

First off I'm using the Doepfer DIY Kit #1 PSU with the board at the moment and have connected this up fine.

Questions:
1. The +5V to the Tune potentiometer (VCO CV_1). I assume this is taken from the +5V connector on the board and wired to the CW pin of the pot, the GND is wire to the CCW pin
2. Is the Fine Tune (CV_SUM) also wired +5V as above to the same pins on the board
3. What voltage is the PW pot wired to +12V
4. What voltage is the VCF Freq pot wired to
5. What voltage is the VCA Gain pot wired to
6. What are the seperate -5V/GND and -12V pins for

and lastly :)

Apart from what is specified in the doc files are there any pots which are specifically Logarithmic

Thanks for you help
