You dont find the effect you need for your live performance? You have a computer, sound card, and want to experiment something new?
I am a MaxMSP developper, i can program an effect that will follow your ideas/dream/requirements for a performance. I have experience of developping a lot of effects for myself as a live performer, I have a Msc in Music Technology and an Engineer Diploma in Programming interactive systems.
I will deliver a standalone Max Patch that can take the ins/outs of your computer or soundcard.
5$: I will make a quick patch following your requirements, it will have one sound source, one mono or stereo output, and up to 3 simple screen-objects to trigger your sound.
+25$: The Patch will be handeling more inputs or outputs (Midi, sensors etc). It will have more objects to trigger your sound, and possibly complex ones. It will need deeper conversation and time for developpement.
+25$: I will make a premium version of the effect, document it, and provide support / advice for your live performance.
