thank you very much for your answer.
As I see, I should not write into forums at 5 am. :)
Too many typos, my bad.
However, I understand what you are talking about.
What I like to to do is to build a musical step sequencer to let them trigger some of my sequencerless analog synths. Therefore I would need CV/Gate on a Doepfer MS-404, maybe on my Roland MC-202, wich has an internal sequencer and should be modified to bypass it, and, for sure, the devices from the Italian Company Coron. They are intended to be triggered through their internal piezo element, that I already bypassed to get them triggered from two Roland TR-606 drum machines, which is quite nice, but somewhat boring as this way I just have a trigger and no note input. So they always play just one note, triggered to the TOM sounds of the 606s.
My idea was to build a seqencer of my own that feeds those analogs with the needed signals.
There are many projects to find trough the net that deal with seqencer stuff. I study them carefully, still learning about programming though, and I believe that I will be able at least to get the synths play different notes and tone length. Maybe, after I learned more, I can add more features like filter tweaks or such things.
As I said, I was searching the net and saw a shop selling the chip mentioned already, and so I asked myself why not also to build a synthesizer using a Teensy that I have here already. And while thinking about it I found this post and dropped my questions.
To make a long story short, I am open for suggestions for my project. :)
I do know about musical synthesizers and sound synthesis, (but I have to say that I knew more about it in my younger years), but I am a newbie in programming and also my lectrical skills could need some improvements, as well as my english. :)
