CODE, FIRMWARE
1. Upload MIOS Bootloader
2. type following commands into the MIOS-TERMINAL:
- set lcd_type GLCD_SSD1306_ROTATED
- set lcd_num_x 9
- set lcd_num_y 1
- set lcd_width 128
- set lcd_height 64
- store
3. Upload the Triggermatrix Code:
the Code 
upload TM4 Code
BUILD
BOM, Components, PCBs
- Full Sized SD-CARD, which is not Hi-Capacity, eg take 4 or 8GB Cards!
- 2x Wood: 15 x 400 x 39mm, or > 16 x 400 x 39mm (39mm is minimal, i took 40mm…)
- 1x Wood: 15 x 335 x 39mm, or > 16 x 333 x 39mm (39mm is minimal, i took 40mm…)
- 3mm Alu Plates for Ground and Backpanel (you cut and drill it by your own)
- 3mm Alu Frontpanel, CNC-machined (See DXF-File for more info)

Features
Short spoken:
- 16xdrumtriggers > Trigger-Routing-Matrix > Drum-Syntesizers
- 5x Poly Melody-lines > Trigger-Routing-Matrix > Melody-Syntesizers (track 1-5)
- 7x Mono Melody-lines > Trigger-Routing-Matrix > Melody-Syntesizers/Pitachable Drums (track 6-12)
Rules:
- Drum-Trigger are Velocity Master > we dont care about the velocity of the Melodys
- There are Songs (ProgramChange), each Song has 8 different Trigger-Routings Presets> these are the Song-Parts
- Each Song has 4 StepSequencer-Variants (Rythms)
- Each Song can Remote up to 6 Melody Scenes (LoopA-compatible!)
- 256 Songs saved on SD-Card, and Load-able while playing
- The Tempo has to be changed by Hand or Midi, it is not saved with the song
- System-Settings, like Ports or MidiChannels are Hardcodet, but there will be a sys-menue in near future
- Triggermatrix midi-outs are connected to all synths, so it manage the program-change also
- 16x Trigger-OUTs with fixed Notes, on one midichannel - to connect Drum-Synths, Drum-Samplers
- 5x Polyphonic Melody-Retrigger-OUTs on 5 MidiChannels - to connect MelodySynths to it
- 7x Monophonic Melody-Retrigger-OUTs on 7 MidiChannels - to connect Monophonic Synths like pitchable Drums or Bass-Synths - i think 1-5 is poly the rest is mono!
- All 16 Trigger & ReTrigger-OUTs share the same Routing and Channelstrip UI (Mute, Solo, Roll…)
- Trigger, Poly, Mono-OUTs can be controlled seperatly by > Random-Kill & Velocity-OFFSet
- 5×16 Melody-Input-Matrix - Route & Mix Melody Inputs to the 16 Melody-Retrigger-Outs (saved in Song)
- 16x Melody-Input-Matrix-Hold-Buttons - hold the last Note, save it in the Patch - usefull when pitch drums.
the Matrix has also a Trigger-Sequencer built in, the Melodys have to come from anywhere else, but @ the end, they have to be plugged into the matrix…
Trigger-sequencer, a few facts:
- is a Drum-Step-Sequencer
- 256 Steps in total
- 32 th fixed rate
- 3,4,5,7,11,13/4 tact
- minimal LoopSection is 16steps = 1 Page, there are 16 pages to chain
- intro LoopSection, from step 0 until to the “minimal LoopSection”- is played once, then it loops the normal LoopSection
- The sequencer is made to give a static NoteStream, the Song-Structure is done LIVE by the TriggerMatrix-ROUTER
- Full Velocity control, visible with 3 different colours, Velocity Set via FADER
- Free programmable Swing to each Step, with 2 different swing Length-sets, which are controlled live with encoder
- copy, paste, erase of pages
- copy, paste, erase of rows\\E
- fixed forward play direction
