Hello there !
I’m working on a diy synth/sequencer for a while now, but i felt that it had to be quite advanced before i can start speaking about it, maybe because i’m a bit shy, maybe because i lack confidence, i don’t know.
I felt that because Olivier work inspired me a lot i had to open a topic here to speak about it.
So here’s the concept :
The “MSX tribute” is a step sequencer based on real hardware chiptune OPLL that was the first fm chip used in MSX cartridge, was the sound chip in the last Sega Master System available in Japan, and appeared also in some Yamaha synth from the porta serie back in the late 80s/90s.
The chip features 9 instrument voices or 6 voices + a drum kit (Hihat, Cymbal, Tom, Snare, Kick).
It has some hardware limitations, such as rom stored instruments and drum sounds, and a 2 operators FM synthesis is available but shared between voices.
Here’s the synth prototype at the moment :
And here are the features :
11 tracks (6 voices, 5 drum kit)
steps parameters :
- tracks parameters :
Octave shift ()
Note Shift ()
Time Scale (from 1/1 to 1/32)
Reset Step (track length)
Gate Length shift (*)
- full access to fm parameters of the chip, 24 in total.
At the moment, i added 3 LFOs, and i’m still working on a solid modulation matrix.
All the FM parameters and the one with an (*) are assignable mod targets.
Every parameter can be stored on an SD card at the moment, and patterns can be changed in live.
Clock can be internal (from 60 to 240BPM, with a resolution of 96ppqn) or sync by midi in.
I’m still working on some developpment at the moment, but i feel that i’m close to something i start to be proud about…
Could someone here tell me about what he thinks about this ?
Thanks in advance
