MOTM

Paul.
i love this encoder pots idea,yes they do sound like the best choice
for a sequencer but they do cost LOTS of mony ,so:
may be you should think of two deferent perpouse sequencer.

1)the most chipe (i meen real chipe) sequencer 16/2 with the worse
pots you can find ,this sequencer would ONLY serve as a programer
of action in the system.
open/close of events just like the mute buton on the softwere sequencers.
it can allso be used for lots of non critical aplication in a system
and ther are lots of this aplication.
make it a 100$ sequencer in we are happy.

2)the second sequencer would be the "player machine".
it would be a 8/2 sequencer built with the great encoders and would
only be used for controling VCO'S, VCF'S or other 1V/OCT units.
but wait ther thats not all,ther should be a smart quantizer built
in the sequencer and a coperator and an acurate glide which is
triger by a toggle switch or an input.
the out put frome the encoder's are binery so a quantizer is the
right element to recive this codes and out put a voltage.
allso this quantizer should have an input so you could patch
in other stuff LFO,ADSR or the chipe sequencer.
allso make a pulse addres and other intresting inputs
and function's UP/DOWN ,RESET,PLENDIUOM,may be a digital memory bla bla
bla....
make it a 500$ sequencer and we done.

thanx
