since i always need quite some time to get into it again, i decided to make a simple visual guide
about how to set up the module for sample playback or live input. i will upload the pdf later if there is interest.
so here are two simple demos of the g0 as a granular sample playback machine:
↑
this is sample playback with a unipolar ramp lfo into the depth modulation input.
depth offset knob is with zoom out in center position, this is the startpoint of the loaded sample.
the attenuation depends on the sample length, speed of the incoming wave and also the Voltage.
so it is quite fiddly to find the right spot but with zoom in it is possible to find it.
grain width is set to very very small which is again appr. the center position of the width offset knob when zoomed out.
i change it a bit during the playback. manual control of pitch to show that pitch and speed are independant.
↑
here i have the same file loaded but changed the modulation of the depth from a lfo to a manual joystick control (planar).
i used the x axis out as sample playback position. since the sample is quite long, the finest touch of the joystick scrubbs
through the sample, right movement gives me forward playback, left movement backwards playback.
the joystick output is unipolar, this is important! at the end of the file i set the y axis out to grain width modulation input,
from there on it's just me playing with the joystick.
↑
pretty much the same setup than with the last speech sample but now with some drum loops loaded.
it was very hard and time consuming to find the right attenuation for the depth modulation input so it is "perfectly"
synchronised to the lfo which moves the grains through the sample. i used a unipolar saw wave lfo and attenuated
it negative into g0's depth mod input, but before that i put it through a polarizer so i could change direction
of the playback to backwards. again the joystick for pitch and grain width control.
although the s0 is more fitted for syncing loops, i really enjoy playing samples so fluidly! for example when i change
the saw to a ramp wave the playback changes to backwards but when i open the grain width a bit more,
one can clearly hear that the grains are still playing forward...this sounds great with transient heavy material like drums!
an envelope follower gets the drum loop and modulates an r-54 filter which receives a copy of the drum loop. some erbeverb.
here is a first sheet for the above playback setup:
and here a simple illustration on how the zoom switch changes the knob behavior:
(Mungo has also a interactive zoom demo here: http://mungo.com.au/eurozoom.html)
an update on this post for some sort of wavetable-ish use of the g0:
(so still in sample / sd card mode)
↑
now before i do the live modes i wanted to show the simple 1V/oct playing of samples on the g0.
it is theoretical possible to use the g0 as a wavetable osc when loading single cycle waveform
(as mungo demonstrates in one of his videos). but i find it impossible to set the grain size so small
that you get a smooth repeating of this single cycle...maybe i'm too stupid or i didn't tried that hard...
anyway i made my own waves, played with different synths to make a few 4-5 second long samples of tones.
some of them are quite static but others had quite some movement and i think the ones with movement
work pretty good for this setup. i played with a doepfer ribbon controller, pitch to the 1v/oct input
and pressure to the width mod input, so when i press harder the grains move through the sample.
manual changing of the grain size. some light eq and delay itb. don't expect music here, this is just me, randomly pressing the ribbon!
and here is the sheet for this setup:
as i wrote above i can make other sheets for the g0 but only if there is some interest in this.
and of course, every hint, help or correction is very much appreciated, i also wrote john about this.
so for example i really would like to understand how the depth modulation input works,
in mungo's manual there is this written: linearly scaled in volts per second of delay/offset time.
this is sadly beyond my current understanding of the module, but i guess my discovery,
that the voltage of the input changes the speed of the playback has to do with this scaling!?!
