gieskes 4swing1c price : $225.00

a module that has multiple functions, vco/vclfo (1v octave), sequencer, clock divider, swing..

the 4swing refers to "for swing" and it has 4 steps. the module can do quite a bit of different things. it can be a clock divider, vco, vclfo, sequencer with swing or without.

gieskes developed it because it wanted a diy version of the doepfer a-147, a module i use allot. but then in combination with a simple sequencer/clock divider, basically a setup they use almost always but then in one module, a bit like this module they used to use allot. the motor bin module uses a binary clock divider, but the 4swing uses a 4017 (decade counter/step sequencer), so it's a bit different. the reason for this is that gieskes wanted swing (they used to use groove allot in lsdj, they think it would be great to have more swing in my eurorack) and you cannot have swing with a binary clock divider.. they think.

features were added based on things i found on youtube, and other sources. for instance the swing was partially inspired by a video by collin benders.
the individual outputs of 4017 step sequencer was inspired by das ding baby 8.
the and gate + 4017 trick i got from peter edwards sequencer.
the 1v per octave tracking vco was smth gieskes learned from moritz kleins video about it in combination with a vco they found by kassu on electro-music forums.

versions:
4swing1a: gate reset input is reset. (this is the most standart version, how it was originaly designed)

4swing1b: two different modes that can be set with the black rate button.
high frequency mode: gate reset input is reset.
low frequency mode: gate reset input is ignored, instead it will hold the sequencer for the duration of the gate signal. (i added this feature because gieskes never use reset in low frequency and the hold feature is verry nice).

4swing1c: same as 4swing1a but with expander module.
2 extra main clock outputs, if which one has a attenuation potmeter.
1 gate hold input for the sequencer steps.
1 lpg.

specifications:
4swing module width: 5cm (10hp), power consumption: +18ma -5ma.
4swing expander width: 2cm (4hp), power consumption: +2ma -0ma.
depths of module and expander about 2.5cm with power cable connected.

clock input: replaces the internal vco as clock source for the sequencer. the vco will still function at the same time, but will be just disconnected from advancing the sequencer.

clock output: active steps of the sequencer, voltage level can be set with a 2mm flat head screw driver, the output signal is + voltage and - voltage, between about 0v and the 22v peak to peak. it focuses more on the positive voltage then the negative.

cv output: the voltage at the current step of the sequencer, 0 to +10v.

cv input: -12v to +12v, controls vco that drives the sequencer, if tuned can track 1v octave over around 5 octaves. there is a tune multiturn trimmer potmeter to tune the 1v per octave tracking, it is located left under the reset input.

reset: resets the sequencer and the vco. (see versions for the difference per versions).

1,2,3,4: individual gate outputs of the step sequencer, 0 to +10v.

start: start or stop the vco.

step: hold the sequencer or make it step forward.

3/4/2: sequencer length.

rate: vclfo or vco. low frequency rate or audio rate.
