Constant descriptions
-
kSynthesizerDynamicVoice
-
Voices can be assigned to parts on the fly with this synthesizer (otherwise, polyphony is very important).
-
kSynthesizerUsesMIDIPort
-
This synthesizer must be patched through a MIDI system, such as the MIDI Manager or OMS.
-
kSynthesizerMicrotone
-
This synthesizer can play microtonal scales.
-
kSynthesizerHasSamples
-
This synthesizer has some use for sampled audio data.
-
kSynthesizerMixedDrums
-
Any part of this synthesizer can play drum parts.
-
kSynthesizerSoftware
-
This synthesizer is implemented in main CPU software and uses CPU cycles.
-
kSynthesizerHardware
-
This synthesizer is a hardware device, not a software synthesizer or MIDI device.
-
kSynthesizerDynamicChannel
-
This synthesizer can move any part to any channel or disable each part. For devices only.
-
kSynthesizerHogsSystemChannel
-
Even if the
kSynthesizerDynamicChannel
bit is set, this synthesizer always responds on its system channel. For MIDI devices only.
-
kSynthesizerSlowSetPart
-
This synthesizer does not respond rapidly to the various set part and set part instrument calls.
-
kSynthesizerOffline
-
This synthesizer can enter an off-line synthesis mode.
-
