Hello all developers. Sorry for, probably, slow and straightfull english. All stand-alone instruments, processors and other modules, controlled through midi, as you understand, currently have a serious disadvantage of audio plugins: user must remember all midi parameter numbers and, sometime, values (aeolus stops switching) in order to controll them via MIDI. It would be nice for all MIDI-managed software, to have capability to send out changes of MIDI parameters when user changes them using native GUI of this software. For example, when user toggles several stops on aeolus, it would send approriate MIDI signals, so, that when sent back into instrument, it will toggle the same stops. So, users could use standalone software as easy as audio-plugins: Aeolus, Yoshimi/ZynAddSubFX (not sure, that all parameters available via GUI), Phasex... Jack-rack, fst and vsthost (dssi-vst), rakarrack, many other. Kokkiniza! ;)
