MBSID V2 Drums Teaser #1


TK.

Recommended Posts

I've worked on the drum engine in the last days. The concept is frozen, most of the code is implemented, and now it needs a lot of testing (from my side) in order to check, if the engine is doing what I initially planned.

So, it was time to work on some teasers!  ;D

Some words to the concept: each patch contains 16 drum patches, which either can be played directly from a MIDI keyboard/sequencer, or from the internal sequencer, which works similar to the bassline seq - means: you can select the sequence via MIDI notes, so that they can be controlled interactively. More words to the sequencer in the next teaser ;-)

Since the memory of a patch is limited, a drum only consists of 8 parameters. But only might be the wrong word, because each parameter changes the drum timbre dramatically!

Instead of editing wavetables, or tweaking on ENVs/LFOs (which can be very time consuming and is not the intuitive workflow you would expect from a drum synth), there are prepared "drum models", which are hardcoded in the firmware. In theory up to 256 drum models can be implemented.

Drum models currently only exist of waveform/note tables. Within the patch It's possible to change the tuning, the ADSR parameters, the gatelength, the WT speed and a special "WT parameter", which modifies a variable part of the wavetable.

Ok, enough details, just listen to the examples:

Bass Drum Model #1 and #2, some parameters tweaked while sound is playing:

Fx Model #1 and #4, some parameters tweaked while sound is playing:

Now it's time to check, how drum and bassline sequencer are working together. :)

Best Regards, Thorsten.

Second Teaser: http://www.midibox.org/forum/index.php?topic=9938.0

how many sound can play this drum mode?

There are 16 instruments per patch, which can be played by 2 SIDs (-> 6 voices which can play in parallel)

With a full stuffed MBSID V2, you could play up to 64 instruments with 8 SIDs (-> 24 voices)

Best Regards, Thorsten.
