We can use T rate cv input as selecting deja vu loop length or start position.
The cv range is from 0V to 5V. The cv value is reflected to deja vu loop value linearly (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16).
During deja vu loop cv input mode, T rate setting is set by T rate knob.
The deja vu loop cv input mode setting is saved to non volatile memory.
- Type1
- T rate cv input works as deja vu loop length cv (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16) mode.
- deja vu knob act as deja vu loop start position (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16) knob.
- This loop start position value is active only in this mode.
- Type2
- T rate cv input works as deja vu loop start position cv (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16) mode.
- This loop start position value is active only in this mode.
- deja vu length knob act as normal function (1,2,3,4,5,6,7,8,10,12,14,16).
- Type3 (added at v9)
- T rate cv input works as deja vu loop start position cv (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16) mode (loop end position is fixed at 16. So loop start position and length are controlled simultaneously). It's inspired from Serge Sequencer.
- For example, loop start position is 1 then loop length is 16. Loop start position is 16 then loop length is 1.
- deja vu length knob acts as deja vu loop start/end position offset(rotate) (CCW is 0, CW is 15). So generally deja vu length knob position is CCW. Loop start position is calculated by adding loop start position cv value (1 to 16) and loop start position offset knob value (0 to 15). If calculated value overflow 16, the value is subtracted by 16.
- This loop start position value is active only in this mode.
- Type4 (added at v9)
- T rate cv input is the same as normal function.
- deja vu length knob works as deja vu loop start position (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16) mode (loop end position is fixed at 16. So loop start position and length are controlled simultaneously). It's inspired from Serge Sequencer.
- For example, loop start position is 1 then loop length is 16. Loop start position is 16 then loop length is 1.
- For example, deja vu length knob position: (CCW is loop start position 1 and loop length 16. CW is loop start position 16 and loop length 1.)
- This loop start position value is active only in this mode.
We can use X external clock input as T trigger rising edge reset mode (x is clocked by internal t clock).
And we can use X external clock input as T gate hold mode (x is clocked by internal t clock).
The X external clock input mode setting is saved to non volatile memory.
- Type1
- X external clock input works as T trigger rising edge reset mode. When trigger/gate rising edge signal detected at X external clock input, internal T and X sequence are resetted.
- Type2
- X external clock input works as T gate hold mode. During trigger/gate ON signal at X external clock input, internal T and X sequence are holded (in another word, pause and resume behavior).
When T trigger reset/hold mode is set, self patching from T1/T2/T3 to X clock input is impossible physically.
So as alternative way, in T trigger reset/hold mode, we can set X clock source.
- Type1
- T1 is internal patched to X clock.
- Type2
- T2 is internal patched to X clock.
- Type3
- T3 is internal patched to X clock.
We can use T jitter cv input as selecting X quantizer scale slot.
cv input value | selected quantizer scale slot |
---|---|
0v - 0.5v | 1 |
0.5v - 1.5v | 2 |
1.5v - 2.5v | 3 |
2.5v - 3.5v | 4 |
3.5v - 4.5v | 5 |
4.5v - 5v | 6 |
During X quantizer select cv input mode, T jitter setting is set by T jitter knob.
During X quantizer select cv input mode, normal (original firmware's) quantizer selected slot setting value is ignored.
Selected quantizer scale slot value by X quantizer select cv input doesn't overwrite normal (original firmware's) quantizer selected slot setting value.
The T jitter cv input mode setting is saved to non volatile memory.
- Type1
- T jitter cv input works as X quantizer slot select mode.
We can use X spread cv input as selecting X quantizer root.
During X quantizer root cv input mode, X spread setting is set by X spread knob.
The X spread cv input mode setting is saved to non volatile memory.
- Type1
- X spread cv input works as X quantizer root mode Type A (adding offset root mode).
- Type2
- X spread cv input works as X quantizer root mode Type B (not adding offset but reflect root).
- Type1,2,3,4,5:
x always quantized with new x steps mapping (CCW 7 o'clock: only rare notes. 12 o'clock: all notes. CW 5 o'clock: only general notes.).
x generates different note from the others x. (Limitation: If variation of notes is a few amount, the same note may be generated.)
- Type2,3,4,5:
Controlling x same note probability. (0V: different note a.k.a. normal behavior. 2.5V: 50% the same note. 5V: always the same note.)
- Type4,5:
Controlling x slew amount. (0V: no slew. 5V: large slew amount.)
- notes:
Type2,3,4,5 replace some cv in or knob to alternative setting (x same note probability or x slew amount). When the knob is replaced, the cv in works as original function (x steps or x bias). When the cv in is replaced, the knob works as original function (x steps or x bias).
We can increase deja vu loop length.
The panel's marking value of LENGTH knob may differ from actual value.
If deja vu loop start position setting enabled, additional step (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16) is also selectable.
The deja vu loop buffer size mode setting is saved to non volatile memory.
- Type1 (Jthrw's)
- 128 (1,2,3,4,5,6,7,8,10,12,14,16,24,32,48,64,96,128)
- Type2 (base 2)
- 128 (1,2,4,8,16,32,64,128)
- Type3 (base 3)
- 192 (1,3,6,12,24,48,96,192)
- Type4 (base 5)
- 320 (1,5,10,20,40,80,160,320)
- Type5 (fibonacci)
- 233 (1,2,3,5,8,13,21,34,55,89,144,233)
We can explore random rhythm and return to the previous discovered random rhythm.
Play scenario is:
- Explore random rhythm.
- Lock the rhythm by setting "deja vu knob" to 50%(12 o'clock) with deja vu enabled.
- (NEW FUNCTION) Save the rhythm
- 3a. long-press "T rate switch".
- 3b. then LEDs run animation. (and detouch from the switch.) (It represents currently in "alternative settings" mode.)
- 3c. then press "T deja vu switch".
- 3d. then "T rate LED" becomes fast-blink in a short moment and stop blink. (It represents saving is executed and "alternative settings" mode exited.)
- Explore another random rhythm by changing "deja vu knob" or switching deja vu enabled-disabled.
- Lock the rhythm by setting "deja vu knob" to 50% with deja vu enabled.
- (NEW FUNCTION) Load the previous rhythm
- 6a. long-press "T rate switch".
- 6b. then LEDs run animation. (and detouch from the switch.) (It represents currently in "alternative settings" mode.)
- 6c. then press "X deja vu switch".
- 6d. then "T rate LED" becomes fast-blink in a short moment and stop blink. (It represents loading is executed and "alternative settings" mode exited.)
Notes:
The knobs position values aren't saved/loaded.
We can select "Markov algorithm" of t mode.
The t mode setting is saved to non volatile memory.
Play scenario is:
- (NEW FUNCTION) Set Markov algorithm of t mode
- 1a. hold "t mode switch"
- 1b. press "T rate switch"
- t mode becomes Markov algorithm. During Markov algorithm mode, t mode LED blinks faster with red color.
- Unset Markov algorithm of t mode
- 2a. press or long-press "t mode switch".
- t mode becomes normal "drum algorithm" or "three state algorithm".
In the normal mode,
-
long-press "T rate switch".
(In alternative settings mode, t deja vu LED, x deja vu LED and X external processing mode LED are animating.)
- press "X external processing mode button".
Saving alternative settings (X external clock input mode, T jitter cv input mode, X spread cv input mode, T rate cv input mode) to non volatile memory will be done automatically when exiting/canceling alternative settings mode.
In alternative settings mode,
- long-press "X external processing mode button".
Then "T rate LED" becomes fast-blink in a short moment and stop blink. (It represents "alternative setting edit" mode exited.) Then all alternative settings values return to default value.
-
It is based on latest official firmware. (So superlock feature is included.)
-
Using the alternative firmware with all normal setting, the behavior is the same as latest official firmware.
