Hi,

I think we've already discussed this, but here's my reguritaion of my
personal opinion...
I suspect effect-design is better done in a specialist program like Reaktor,
Tasman or SynthEdit.
IMHO The target of the GIMPI plugin system is the user who thinks "This song
needs a reverb", click, click done.
NOT the person who thinks "I want to design a new type of reverb, where's
my comb filter?".
On the surface these two things are similar ( a graph of audio processing
objects ). But when you get down to the details, the requirements diverge
sharply. An interface like VSTi or DXi needs to be simple to implement and
efficient. I predict GIMPI will use block-based processing?
Yet, software like Reaktor, Tasman, or SyncC modular where you can design an
individual filter, NEED single-sample feedback to create recursive
structures (filters, delays, and physical models). In order to remain
efficient, you need to support single-sample processing, which is TOTALLY
different to implement. It is also crucial to support 'silent' samples and
CPU-saving techniques at the plugin level. And don't mention polyphonic
support... The user draws the graph once, but the host has to duplicate a
sub-graph for each voice of polyphony. Not the entire graph, the host
performs complicated analysis to determine which objects are polyphonic, and
which monophonic.
As the writer of SynthEdit, I've written both types of code. I honestly
believe that if GIMPI trys to be too general, everything to everyone. It
will be an over-complicated mess. GIMPI needs to stay focused and tight.
There's plenty of software for low-level design already, and it all supports
being imbedded in an existing hi-level plugin standard like VST.
Best Regards,
Jeff
