A module that is able to switch several signals was suggested independently by several musicians who use the A-100 live on stage. They wanted to have the possibility to switch simultaneously several CV and/or audio signals (by hand or CV controlled) to make the music more diversified (e.g. to generate breaks). The A-150-8 is the result of these suggestions. In general there are more and more musicians who ask for live performance tools. The performing mixer modules A-138o/p and the planned voltage controlled performing mixer modules (A-135-4A/B/C) also follow this direction. Best wishes Dieter Doepfer

thanks, Dieter, for the info. with the A150-8, is the audio source switching been made seamlessly ? or there are 'clicks' or other type of noises in the audio path? if the audio source switching is seamless then, indeed, the A150-8 could be very helpful in various situations. best regards,Bakis.

The A-150-8 includes 8 switches. A "smooth" transition cannot be generated by a switch but requires special VC crossfaders (i.e. 16 VCAs with 8 voltage inverter circuits and 8 slew limiters). This would be much more complex and expensive. And it would no longer work in both directions. Best wishes Dieter Doepfer

One of the usages I see for this module is to use it along side a CV programmer module (like our Synthwerks PGM-4X4 - http://www.synthwerks.com/pgm-4x4.html <http://www.synthwerks.com/pgm-4x4.html>) to not only program CV voltages but also change patch cords for primarily live performance. We have designed a variant of our PGM-4X4 called the PGM-4X4S which replaces the pots on the standard module with jacks to provide a manual/gate/internal sequencer switchable 4X4 array of bi-directional switches for just this purpose too. Though useful in the studio, they are aimed at the live performer who wants to switch sources/destinations of parts of complex patches without having to re-patch cables live. These switches, like almost all switches like them, will cause clicks or pops if you are switching audio through them. This cannot be avoided unless you have circutry that detects the zero crossing of the audio waveform and switches only then, or has VCA’s and does quick ramps between switch states, both that add quite an expense to the module. In a live situation, the switches would have their states changed most often between “songs” so these clicks would not be heard. -James James Husted, Designer, Synthwerks LLC • www.synthwerks.com <http://www.synthwerks.com/> • james@synthwerks.com <mailto:james@synthwerks.com> • info@synthwerks.com <mailto:info@synthwerks.com>

thanks Dieter and James for your replies. it seems i expected too much of the octal switch module. anyway, indeed it would be very helpful in live situations. i might include one in my live doepfer setup. best regards,Bakis.

I have thought of trying to make a switch module using a set of Vactrols as the switching elements. The inherent lag in Vactrols would not click but it would not be exactly cheap either, and it would’t be fast but it wouldn’t click either. Might be interesting just to check out. -James James Husted, Designer, Synthwerks LLC • www.synthwerks.com • james@synthwerks.com • info@synthwerks.com

I am afraid that the world became quite “choosy” along the decades as for the pursuit of sound “quality”. The trend strongly arose out of the DSP advent, at large, though the quest after aseptic and free from contamination soundscapes surely is an old story… By the way, it always surprises me, since it seems a pretty empty concept from a creative viewpoint or... just sterile and inconsistent. Do not noises and clips and thumps and bums and hums take part anymore in music and creation, as well as in life and natural processes? best, Diego Il giorno 07/feb/2017, alle ore 16:25, yahoo@doepfer.de [Doepfer_a100] <Doepfer_a100@yahoogroups.com> ha scritto:

I, kind of, agree for some things that is fine. and and a nice artifact...sometimes. When it happen at every switch, that gets old fast--depends on material. That "click" may become an irritating side effect in many cases IF used with audio. Has nothing to do with "sound quality” That should remain the same.

eventually solo and mute buttons do exist on channel strips as well as routers and patch bays - absolutely smooth signal flow - feel free to unchain modular signals reaching the outer world - the A-150-8 will be the further smart utility Il giorno 08/feb/2017, alle ore 06:12, 'p. hendricks' ph@comcast.net [Doepfer_a100] <Doepfer_a100@yahoogroups.com> ha scritto:
