Synthux Academy Spotykach Cheat Sheet (DRAFT) by

Spotykach is a dual-deck time-traveling looper that lets you record, twist, slice, and drift through sound history. Inspired by reel tape (1960s), digital slicing (1990s), and modern algorithmic chaos. Built for live experimentation and open-source hacking. Sporting colors taken from the device itself, this sheet fits on one printed page, if barely. I will do my best to keep the sheet up-to-date with firmware changes as they are released. Please join the Synthux Spotykach discord to discuss!

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Common Controls

Routing Switch
left (mono)
Two indepe­ndent mono decks (input and output)
center (stereo)
Inputs hard-p­anned and routed to both decks. Outputs contain stereo mix of both decks.
right (mystery)
TBD
Core Controls
tap
tap tempo
alt + tap
toggle external clock
alt + play (while stopped)
arm recording
play
toggles playback of the deck loop
alt + play (while playing)
engages overdu­bbing
play (while overdu­bbing)
disengages overdu­bbing
alt + pitch
snaps to: +/- fifth, octave, 2 octaves, zero
reverse
moves the playhead in reverse
alt + reverse
engages resampling / deck-t­o-deck recording
mixer slider A <--> B
mixes output of decks A and B; center = both simult­ane­ously
alt + mix
sets the feedback level of the overdu­b/delay effect
alt + sequence pad
engages trigger sequencer recording
alt + sequence pad (hold 2s)
deletes that deck's sequence
tap (hold) + deck A mix
adjust metronome level
tap (hold) + play
load the recording from sd card
tap (hold) + reverse
save the recording to sd card
CV
gate in
triggers the playhead
gate out
TBD
clock in
4PPQN clock signal
pos & size in
controls position, size, or both (dependant on related switch)
mixer in
controls mix
Note: when mixer in is patched, mixer slider becomes Deck A offset
envelope
adjusts shape from no/sharp thru flavors of attack­/decay
 

Modulation Sources

switch
switches between envelope follower (up) and two LFO shapes
cycle
LFO modes: LFO rate
ENV Follower mode: controls attack & release
glow
LFO modes: LFO attenuation
ENV Follower mode: volume compen­sation

FX: Grit & Flux

fx pad + tap
switch current effect
Grit (orange, textur­e-b­ased)
orange: bit crusher
grit fx pad + pitch
softer <--> harsher / lower bitrate
grit fx pad + mix
fx output gain
yellow: analog saturation
grit fx pad + pitch
saturation <--> distortion
grit fx pad + mix
fx output gain
Flux (pink, time-b­ased)
pink: tape delay
flux fx pad + pitch
change tape delay speed
flux fx pad + mix
delay output mix
flux fx pad + pos
delay feedback
 

Reel Mode

Inspired by 1940s and 1960s tape music. This mode is monoph­onic, where time and pitch are bound together (like real tape).
recording
starts when input signal crosses threshold of -40dB
pos
determines loop start point
size
determines loop length

Slice Mode

This is a polyphonic looper, where pitch and time are discon­nected (time stretc­hing).
recording
starts / stops quantized to clock (next quarter note)
pos
determines slice start point
size
determines length of slice
alt + size
CCW: monophonic - CW: polyphonic
Slice mode does not support overdu­bbing!

Drift Mode

Designed for generative and granular textures.
recording
starts when input signal crosses threshold of -40dB
pos
moves playhead: where to generate grains from
size
grain distri­butino: how wide an area around playhead to generate grains from within
alt + envelope
envelope length (re-tr­igger period 40ms..5s?)
alt + size
window size / density (grain size 40..50­0ms?)
