Using the toolkit provided with renoise… I do lots of “morping” synths…
it can really sound killer indeed… the only problem is… its never a straightforward morph… need to play with lfo-curves and all kinda weirdness to make it sound as great as you imagine your function to sound.
then again… morphin synths where possible on my mc909, where you dindnt have all these fancy tools, just some filter and amp-mixing tricks… and that was groovy as well… the trick there was you just gave startingpoint and endpoint… and did reverse on the other voice… all connected to 1 rotary… thus you could raise amp and lower amp simultanious in 2 voices… or do that + filtertrickery…
didnt the a4 have somesort of performance-tool to do exactly that ?
