Hi,
some month ago I had the S1 for testing. One target was to exploit its midi capabilities.
But then I forgot to publish the results in Casio Forum - finally here it is
In short: There's not much that can be done to 'CT S1 keyboard layer'.
But CT-S1 has also an inbuild GM sound layer. This layer contains the standard 'GM-1' sound palette but also the CT-S1 'keyboard' sounds (including the vintage synths).
The GM layer can be 'played' with external keys (midi keyboard + usb-host) or by sending midi note/on-off from the CTS1 keys back into the GM layer.
For the latter purpose one can use e.g. the (free) Android-app 'Midi-Commander' for which I made a little setupfile
Using the GM layer offers additional features:
1. increased multi-timbrality: in theory one can layer all 16 midi channels + 2 CT-s1 layers ... in real life, CT-polyphony of 32-stereo makes this soon an end ;))
2. modding sounds by standard GM midi controllers, as there are:
pitch, mod, panpot, damper soft/sostenuto/sustain, filter-cutoff, ADR-envelope, vibrato, portamento, reverb, chorus, master-tune
This is extremely nice when applied to the VX/CZ patches - I could create some very nice synth sounds
('glitch': GM filter-resonance does not work - maybe a bug or limitation by performance)
Now what does the 'App' do? Connected to the CT, it:
- receives Note-On-offs from the CT keys an send them back to a GM layer
- allows to use the GM controllers to modify a sound (live)
- allows to create 'patches' for loading sounds from GM layer (including 'GM-1 and CT- sounds) and adding GM-controller modifications
A resumee of the CT-S1 GM midi stuff and a MidiCommander setup file is included in the attached zip-file (if someone tells me which category to use for CT-1s I can also upload it to the download section)
