dsp chung is a free universal dsp sound effects program for your computer
.Chooze the input sound port (for example the line in entry of an
external usb sound card) then dsp effects (autovol/compressor , reverb,
automodulation, decay, plugins compatible with midipiano_chung) will be applied and sent to the selected output sound
port (for example the system mixer) . The program is written in compiled
freebasic , source code is included in the zip file . Can be connected in feedback loop input from and output to the system
mixer, a button "testloop" adjusts gain to avoid larsen oscillations ,
and add amazing reverb decay to the overall computer. re-discover youtube music with this.
example of use : connect the entry to the system mixer and the output to the system speakers to add reverb decay to your ambient sound (beware of larsen effect).
can be used as a single virtual active audio cable.
if you have an input entry on your synth piano you can connect dsp input to the output of the synth and feedback output to the input entry , automod will simulate piano's deformation and modify the timbre.
tips: activate and record the sequencer at least once to add sequencer settings that enhance the overall sound even if you return to instrument mode or switch off and reuse the keyboard
however , for listening midifiles i prefer midipiano_chung , even if with midivelo_chung and the dual layer function the ctk6200 becomes fantastic .
you can also connect dsp_chung between lineout and linein of the ctk6200 to add external reverb and decay effect , i have added a "testloop" button to adjust gain to avoid feedback larsen oscillations .
note : the ctk6200 alone is not bad too.
I have updated autochord / brainchord function of midipiano_chung / brainpiano_chung / brainpiano2 chung so it can add chord generation to any melody (even single notes) from another song without too much detune .
connected to line out / in of ctk6200
