Parameters (16)

NameTypeRangeMin FWBehavior
BPM knob 10BPM – 300BPM — Master tempo, 10–300 BPM, set via the program knob. [1]
Delay menu_setting — — Percent of total step time before waveform generation starts. Requires Dly to take effect. [1]
Dly menu_setting — — Delay divisor: which steps the Delay parameter applies to. 1 = every step, 2 = every other (swing), etc. [1]
ERot menu_setting — — Rotates the Euclidean pattern by N steps. [1]
EStep menu_setting — — Number of steps in the Euclidean pattern. [1]
ETrig menu_setting — — Number of triggers (hits) distributed across EStep. Must be less than EStep. [1]
Level menu_setting 0% – 100% — Output voltage level as percent of the 5V maximum. [1]
Logic menu_setting — 205+ Per-output AND, OR, or XOR with another channel's output. [1]
Loop menu_setting — — Loop length in beats. Resets random and Euclidean state. Setting to 0 re-seeds the random number generator. [1]
Mute menu_setting — 189+ Mute or unmute an output. Output remains editable while muted. [1]
Offset menu_setting 0% – 100% 189+ Vertical offset added to the output. Voltages over 5V are clipped. [1]

Width menu_setting — — Width parameter; effect depends on selected waveform (gate duty, triangle/sine skew, envelope release, smooth-random sharpness). [1]

Firmware history (19 versions)

VersionReleasedNotes
207 — Tweak to logic handling to avoid potential short 'ghost' triggers based on logic ordering. [3]
206 — Fix minor issue with step up output type getting rendered incorrectly. [3]
205 — Added Smooth Random waveform type. Added Logic parameter (AND/OR/XOR). Fixed small blip in output when rotating outputs. [3]
204 — Added sample and hold to quantized random waveform when rhythmic patterns (rskip, eucl) applied. Manual updated. [3]
203 — Renamed scales to 'mr hooks' suggested notation. Added Phrygian scale. Fixed issue where special modifier types weren't getting saved correctly. [3]
202 — Added QUANT quantizer channel option with basic scales. Added new run type for bank selection via voltage level. Fixed PPQN screen, CV reset of random seed, CV modifier assignment bug, and mute state on full reset. [3]
201 — Support for improved BPM representation requiring Rev 063 board. On Rev 062 hardware, firmware has no improvements over 200. [3]
200 — Version 199 tweaked to support newer Pam Rev 062 hardware with different DAC chip. Only for Rev 062 units; will not work on older hardware. [3]
199 2018-01-16 Fixed bug where stopped BPM changes lag one beat at clock start. Improved random seed distribution across outputs. Fixed expander sync with external clock. Fixed outputs starting with phase offset. [3]
198 2017-10-25 Fixed output end pulse type may not fire. Fixed CV of looping not working correctly. Load next (not prev) bank when CV1 is low. Allow external clock with new run options. Extended screensaver timeout to 15 mins. [3]
197-BETA-2 2017-09-14 Improve VC control of tempo. [3]
197-BETA 2017-08-17 Various bug fixes and tweaks to run input and rotation. Added single row (upper 4 outputs) rotation mode. [3]
197-ALPHA — Load/Save display last bank used. Run input can load next/previous full save bank or rotate outputs (direction depends on CV1 high/low). Output multiples/divisions can be changed without cycling through every option using push-hold-twist. [3]
196 — Another attempt at making slop behavior more predictable/natural. [3]
195 — Tweaked program knob handling. Fixed voltage control of euclidean params. Improved clock calibration resolution (now 0-100, below 50 slower, above 50 faster). Added basic screensaver dimming OLED after 10 mins. [3]
192 — Fixed run input not working when external clock not patched. [3]
191 — Fixed slop parameter so de-slopped outputs fall back into sync. [3]
189 — Added output muting. Added vertical offset parameter. Improved expander MIDI compatibility. Increased CV handling precision. Fixed CV2 attenuversion handling. Fixed keep work bank synced across power cycles. Fixed expander run signal left high when clock stopped. Fixed Euclidean edited outputs reset. Allowed utility modifier outputs to be saved and recalled. [3]
