CV from channel 2 can be patched to channel 3
with offset turned on. Changing the attenuator
in channel 2 will not affect the offset. Also, an
offset from channel 1 or 3 can be patched to an
inverting input of channel 2 or 4, thus a nega-
tive offset can be easily achieved.
MiXinG
A cascaded arrangement of summers allows for
the mixture of all channels with the ability to
break the sum into two sub-mixes. To mix four
signals, feed them into inputs
1
and adjust the
level knobs
4
. The resulting signal is available
at the all socket
8
(make sure that nothing is
plugged into 1+2 output socket
9
). Additional-
ly, you can use the inverting inputs
2
to mix up
to eight signals.
To use Samara as two independent 2:1 mixers,
use both 1+2
9
and 3+4
8
output. Patching a
cable to 1+2 output breaks the internal connec-
tion, and these two channels are no longer mixed
with channels 3 and 4. Again, using the inverting
inputs allows for two four-component mixes.
Since mixing multiple hot signals with little at-
tenuation usually yields overdrive (especially
at the ALL output
8
), a soft-clipping solution
is offered. It can be turned off by removing the
jumper at the batck of the PCB. Additionally,
optional -6dB (2:1) attenuation is available in-
dependently for 1+2 and 3+4 summers by using
two jumpers on the back of the module. Switch-
ing just one jumper does not affect the ampli-
tude of the second summer. Note that the all
mix will have unequal proportions in such case.
Also, note that the jumpers do not affect the op-
eration of the min and max outputs (see below).
MiniMuM & MAXiMuM OutS
In addition to linear mixing, Samara features a
precision min/max computing circuit that out-
puts the current minimum voltage of all the (at-
tenuated) channels at the min
10
output, as well
as the maximum voltage at the max
11
output.
output. See fig. 2 & 3 for examples.
This circuit is intended for processing control
voltages, such as LFO waveforms, envelopes,
etc. However, it does provide interesting re-
sults with audio signals when used as a flexible
