Instrument level is high impedance, very low voltages (same as mic/electric guitar). Synth Audio and CV levels can have form 10 to 20 v swing. Audio is bipolar (+/-5v up to +/-10v). CV can be bipolar or positive only (+/-5v, +/-10v, 0 to 10v)</div><div><br></div><div>4: depending on which circuits you are building, you will need either 12v bipolar or 15v bipolar.

I happen to be studying electronics and having interest in synthesizers (from a user perspective) at the same time and I think it's time to connect them. So I have some questions!</div><div><ol><li>Are there any no-brainer/commonly used parts and ICs used particularly in audio modules and which I should buy in larger quantities? For example, in university I got along with HC14/AC14, BC547/557, 555, µA741, LM358, LM385 and TL431.<br></li><li>I was taught that structures like Eccles-Jordan circuits are archaic and we shouldn't use them, but is this also relevant in analog synthesis? Any other examples?</li><li>I can't find any good materials explaining typical audio voltage levels? I'm talking about line level. instrument level, signal from microphone/electric guitar, and most importantly CV and voltages used in modular synthesizers.</li><li>I'm assigned to make a linear power supply, and I don't have any specific parameters specified. Could you suggest what voltage level and power it should probably give so I could use this in future synth/audio projects?</li><li>Are there any good wikis/sites/forums for people like me? It was really tough for me to find anything except this mailing list</li><li>Is there anything else I should probably know?</li></ol><div>Cheers,</div></div><div>Bartek</div></div>
