the microsoft gs wavetable synth (such as default in in Food for PhraseTouch) never work on my pc s, presumably the sound card
can be solved with a virtual midi driver
First of all, point out that PhraseTouch does not just do things with phrases. In essence, shooting a phrase is the same as shooting a note, and this opens up many possibilities, just as this tool is designed. Also, the PhraseTouch name does not have to be related to the Renose phrase XRNZ format. You can compose your own phrases with PhraseTouch, writing notes, chords, rhythms, etc.
That said, the configuration with the wavetable can be replaced by the loading of a VSTi for each instrument. The problem that I see is that in the instrument box, the name of the type of instrument that should sound for each phrase does not appear. This can be a bit confusing. You need to hear the phrase to know which instrument corresponds and then load the VSTi (or samples), so that it sounds better.
PhraseTouch allows you among other things to trigger the same note of several instruments at the same time (up to 16 instruments). This can be used for specific percussions, or sound textures formed by several samples that sound at the same time. But it will also allow you to simultaneously trigger your associated phrases through the Keymap of each instrument.
But the libraries, and no other current format does not allow the multiple loading of several instruments or phrases, in a single operation. If this were possible in the future, maybe it would be easier to deal with these things.
What I see is that there are too many steps to reach the end of the result, what you want to hear about this work. Try to reproduce the phrases. If your sound card does not allow you to play sound with the wavetable, these packages will not help you. The issue is to replace each instrument with a VSTi instrument or samples.
