the Ti Desktop (currently) does not have an exact display for how may voices
are in use / still remain ... nor a overall peak meter for system resources.

there's only some meter in the top right corner of the display which shows the resource utilization of the patch - so it's hard to give a precise answer.

like Timo wrote before ... it always depends on how many oscillators are in use and to which level Unison is set (1-8 Voices).

math example: 3 OSC * Unison x8 = 24 voices (max. utilization per patch)

hint: you still could reduce Unison level, if it's hard to the 50 / 80 voices limit.
