Hi,
I was talking to a friend this morning about a project I thought we

could do together. He plays free improv piano/keyboard music - dense

patterns and textures improvised in live time. I was saying that in

principle it would be possible to record a piece of his music on a

keyboard as a midi stream, then feed it through a softsynth in a studio

and tweak the synth parameters as it's playing to produce the final piece.
He liked the idea, but I'm not sure if there's a linux softsynth that

would work like this. What it needs to do is:
- produce sounds from a midi stream in real time, with the sound altered

by tweaking various parameters (knobs and buttons).

- the tweaks should be recordable so that you can play them back and

re-tweak them until you get the result you want.

- the feature I really want is to be able to set presets for the

parameters and then fade between presets in real time. E.g. if there are

two presets which both use a resonant low pass filter, I want to be able

to move a single slider that moves the filter value from one to the

other continuously to create a filter sweep. This is different from a

fade at the audio stream level.
Does anyone know of anything like this?
cheers,
andy
