Tutorial: https://youtu.be/1SCG_FcJc24
To load onto Teletype, download the .txt file, rename to the scene slot you wish to overwrite (e.g. tt07.txt) and drop on a thumb drive. Insert into Teletype and commence jams.
TELETYPE I/O:
- LEFT SIDE: CHORD SEQ
- CENTER: SET LOOP START+END (USE 2 FINGERS TO SET)
- RIGHT SIDE: ARP SEQ
- IN 1: ADVANCE CHORD
- IN 2: RESET ARP
- IN 3: ADVANCE ARP
- CV IN: CHORD SPREAD/VOICING
- PARAM KNOB: SCALE
- TR 1: CHORD TRIGGER
- TR 2: LIVE CHORD TRIGGER
- TR 3: ARP TRIGGER
- TR 4: LIVE ARP TRIGGER
- CV 1-3: CHORD
- CV 4: ARP
SCALES:
- 0-major
- 1-natural-minor
- 2-harmonic-minor
- 3-melodic-minor
- 4-dorian
- 5-phrygian
- 6-lydian
- 7-mixolydian
- 8-locrian
SCRIPT NOTES:
- $ 1 Triggers chord sequence advancing, CV and TR out
- $ 2 Spread/voicing algo for chord CV, triggers reset of arp section
- $ 3 Triggers arp sequence advancing, CV and TR out
- $ 4 Handler for sequence advancing (P.NEXT, reset, setting loop start/PN.L)
- $ 5 Sets dim previous/reset loop button LEDs
- $ 6 Looper column button handler
- $ 7 Sets loop variables post-handler
- $ 8 Sequence button handler (including live play triggering)
VARIABLES:
- A Enable Chord P.NEXT
- B Enable Seq P.NEXT
- C Current Chord
- D Local var for $ 8, + Init (via Metro)
- X Loop BTN GRPI (8/9), + Init (via Metro)
- Y Loop BTN -8 (0/1)
- Z Indicates Chord/Arp (0/1) when calling $ 4
- T Local var for $ 3
- R IN + modifiers
- PRT 7 Metro/Init
- PRT 8 PRM/Scale
- PRT 9 Raw IN/CV
