So i looked through the schematic and found that all the vca/vcf chips get routed to one op-amp. before the op-amp they use a simple mixer (a resistor of, if i recall it was 3megs for each output of the 6 voices) to combine the 6 voices before they enter the uninvented side of the op-amp...<br />So i de-soldered 5 of the resistors, and routed them to 5 switches out the back. So now the voices go out form the original simple mixer to switches then back through the resistor value then into the op-amp. <br />Now when i play in unison mode i can choose how man voices i want on against the un-effected one.... any way it works great the other voices go to ground when switched off and now i have a bad ass Juno 106 mono synth.Prince.Cobrahttps://www.blogger.com/profile/12606834658357567205noreply@blogger.comtag:blogger.com,1999:blog-279251740880432906.post-39938059874096971712010-04-17T20:30:16.215-05:002010-04-17T20:30:16.215-05:00Nice post!

I think my crystal is producing an out of tune C these days...<br /><br />I had noticed the change in the DCO frequency with rapid CVs. You can tell it's a cycling when you hit the keys fast. Interesting to read about why that is happening. I thought I had yet another problem with my Juno.Wallstreethttps://www.blogger.com/profile/05780575198629710473noreply@blogger.comtag:blogger.com,1999:blog-279251740880432906.post-19671190619177817722010-02-11T04:52:03.038-06:002010-02-11T04:52:03.038-06:00great somebody analyzes this and explain it.
I wo...great somebody analyzes this and explain it.<br /><br />I wonder how the chorus works on these synths, that's what makes them popular nowadays, the fat sound (Never played one though).Benjamin Budtshttps://www.blogger.com/profile/12317998622005959876noreply@blogger.comtag:blogger.com,1999:blog-279251740880432906.post-68019356401971016482008-02-18T13:05:00.000-06:002008-02-18T13:05:00.000-06:00Again a good and easy to understand text. Thanks !...Again a good and easy to understand text. Thanks !<BR/>But I found a little error: the schematics shown says: A/D converter left of the current limiting resistor.Qwavehttps://www.blogger.com/profile/09060554869241907412noreply@blogger.comtag:blogger.com,1999:blog-279251740880432906.post-58968194388931538082008-02-18T12:55:00.000-06:002008-02-18T12:55:00.000-06:00please email me I live in Madison..inducejack@gmai...please email me I live in Madison..inducejack@gmail.comRevoJakhttps://www.blogger.com/profile/04921475553859462732noreply@blogger.comtag:blogger.com,1999:blog-279251740880432906.post-62187444561035576202008-02-18T12:53:00.000-06:002008-02-18T12:53:00.000-06:00Wow this is great!!!

I am actually looking for a new analog synth with juno or sh101 characteristics.. Currently I only have a future retro revolution that is the only true analog piece I have... Your dont have anything for sale do you? Great to meet you and thank you for the post..MarkRevoJakhttps://www.blogger.com/profile/04921475553859462732noreply@blogger.com
