FW update to peak/summit - gives 10 user wavetables, AND an editor in componants. You can literally draw a wave shape with a pencil into each of the 5 wave shape slots, then morph between them..... Can also load samples as well, so you can load part of the sample - or all of it, into with one wave slot or across the whole 5.
You can change the harmonic content of each table - and its phase as well as well.
