Waiting for contributor access at the moment, but the interested reader may get these from my github.
mdapiano and mdaepiano
Ports of the venerable MDA Piano and E-Piano plugins. Many thanks to Paul Kellett for open-sourcing them! Both can be used in a 16-voice poly subpatch, where they use around 75% DSP.
These use a sample of about 1mb in size, but when using multiple voices it is loaded only once to save some precious sdram.
For the piano, there is an attribute to disable the stereo comb filter. The reason for this is that this was a per-synth thing in the original vst, so doing it per voice on the axoloti is quite wasteful. It could be replaced by a similar stereo effect outside of the poly patcher, and save some DSP.
