CODE, FIRMWARE
Install MIOS Studio, connect TM4 via USB, and Start the STUDIO
1. Upload MIOS BOOTLOADER
2. (only needet for Virgin Machines) type following commands into the MIOS-TERMINAL:
3. (for Version Updates) Unzip the TM4-Firmware, and Upload the TM4.hex
4. Unconnect USB & Connect the USB again — finished.
5. If the Machine is not detected by mios studio, and you already checked the usb-connections, the device or the code is broken, for that on the backside of TM4 is a switch, please set it to “bLOAD”, now you can upload new & unbroken codes, dont forget to set it to “normal” back again - after upload new code - else the APP will not boot…

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
