The DLSSynth is actually pretty suited to this kind of usage - there
are a number of editors for both sound font and DLS files, it will do
the pitch shifting for you, volume (just use different velocity
values), reverb (or not - depends how you author the sound), panning,
etc...
As for the pitch change - yes we realised that this was missing, so
we've added for Panther a rate control converter unit - it will pitch
shift...
That's a very good news. Is it suitable for a "heavy" real time usage
(e.g. as a pitch shifter in a MusicDevice rendering say 64 notes)?
The pitch shifter in the DLS synth is a less expensive algorithm than
the Varispeed unit... There are many variables that determine how many
notes the synth can play, and it depends of course on how much CPU you
are willing to give to it. There are also some quality and CPU load
properties that you can balance this with - I would recommend you try
this with some simple MIDI files...
The two units are quite separate and unrelated...
Could it be possible that this pitch shifter be available in Jaguar
and not only in Panther (Panther is certainly a must have, but it may
take some time to convince customers :-)
Yes
