Tech Specs: To obtain the HOLD function we had to insert a little time constant in the
circuit and this leads to an audible 'slew' when you drive, for example, the pitch of a
VCO .Is it important to lift the finger quick when you want to minimize this effect... You will
learn this in no time :). A quick hint if you want to play 'theremin' style with the ribbon:
reduce the range of the ribbon (remember, 5 Volts is equal to 5 octaves!!!) with an
attenuator and set the starting freq of the VCO with its TUNE knob. The ribbon is really
expressive when you learn to use it correctly and subtle variations in the finger position
results in pleasant (or NOT) modulations.

MIXER (1:1 and 1:3) :
Those humble modules are actually, together with the sum/sub, one of the most versatile
ones in the NS1nanosynth, with regards to their standard, intended behaviour. As we
choose to mantain all the CVs and signals in general unipolar and 0 to 5V, the MIXERs could
serve many purposes. Punk VCAs, waveshapers and switches! The 'secret' is the 'saturating
voltage' of the mixers and sum/sub blocks. We choose to power those circuits with 5V and
as you may know (or not, given some thread in some famous forums!) the voltage at the
output of a summing static active circuit will NEVER go beyond the power supply rails :).
Whit this in mind we designed two simple mixers types, one with the implicit reduction of
the input channels to 1/3 of their voltage (hint: attenuation) before summing and the other
two mixers with a 1:1 ratio before summing. The first one is clearly identified on the NS1
with "MIX/3" label. The idea behind this /3 was to be able to sum the output waveforms of
the VCO (for example TRI+SQU+SAW) without clipping, and then distortin the resulting
waveform. The mixers have, in practice, another usable quirky aspect. The 1:3 and 1:1
behaviour is only true when all the channel are used or referred to a known voltage. When
you leave unconnected the inputs the mixer will change the gain depending on the number
of the used inputs! This could sound complex and awkward but it's just another tool in your
toolbox! If you don't want this you can just connect to 0V the unused inputs!
Manual Controls: NONE Input/Output: three
channel inputs, one output. Tech Specs: already
discussed!

MULT multiples:
Not many things to say here... there are a few multiples scattered around the board. Use
them to connect more than one cable to one input/output etc.. They are also useful as
extensions!
Manual Controls: NONE.
Input/Output: they are the same.
