the A155 as a graphic vco!!!!

listen to doepfer himself(well and me...): "BAKIS:also,can i use the a155 as a graphic vco???i know that if i clock the a155 using a high-speed lfo it will produce sound,right?? DIETER:Right. But to speak the truth we never checked the max. input frequency of the clock signal for the A-155. But I'm sure up to 10kHz there should be no problem. BAKIS:(but the a155 produces a dc signal...) DIETER:If you use a AC coupled module for the output (e.g. the "old" A-130/A-131 or any filter) the DC is converted into AC automatically. The difference is simply a capacitor in the input stage of the following module. One may built a simply DC-to-AC converter with a special cable that includes a capacitor (e.g. if you would use a A-130V2/A-131V2). BAKIS:but can i make the a155 track the keyboard?? DIETER:Simply trigger the A-155 from a VCO running at higher frequencies (the A-111 will be the better choice as the A-110 scale is OK only up to about 8kHz, the A-111 should work up to about 25...30kHz). BAKIS:if not,what do you think about releasing a graphic vco?? DIETER:It would be nothing but the fader version of the A-155. I designes a graphic VCO with 16 faders and integrated high-speed VCO about 20 years ago. But the inquries were not very good due to the high costs (about 350.00 Euro)." ===== synthfreak(parallel worlds) athens-greece [Doepfer_a100] group owner-moderator __________________________________________________ Do You Yahoo!?
