Analogue systems

Wouldn't it be great for AS to release a new VCO?  Their rs95 is so  
wonderful... now I am looking for an excuse to get a new VCO.  Here  
are some features I would like to see.

1) Keep the 12 HP format, it fits my system well.

2) Perhaps add linear/exponential response switch for the variable CV  
input.

3) Some kind of square to triangle morph?

4) On the triangle/saw morph, keep the voltage a continuous function  
of time until you get to saw.  i.e. Increase the ratio of slope  
magnitudes of the falling and rising part from one to infinity, rather  
than inserting an increasingly big jump.  I don't know how feasible  
this is with analogue circuits.

Any other ideas?  Some kind of crazy waveform perhaps?

speaking of VCOs, I wonder if anyone has compared the older RS90 with the current RS95? Do these share a similar sonic quality, or are they really different beasts?

I was wondering just that.I recently aquired an RS 90 and was wondering how
it compared to the RS 95.
Just in case I would like to get more...

Ernst.

There was a thread on that on the synth-diy list on 2008-12-02
under the subject "VCO design question". It can be done, cf. the
MS-20 LFO. But it's not voltage-controlled and what is easy at low
frequencies might not be at audio frequencies.
