Hello!
1. The problem is that Polyphone cannot import samples with long names and reduces them to short names. But it can open existing samples with long names without any problem.
2. The external command is a good feature, but unfortunately it works badly. Editors can't save changes and this is useless for batch processing. The only way is to export samples and run the batch processor in the editor. But the only thing we need is a VST processor in Polyphone for selected samples, just like EQ, which is already done. Please add this feature )
3. Please add Bassmidi engine for internal polyphone audition. Modulators, reverb and chorus in Polyphone and BassMidi work differently, so we can't guess the final result of our work like in a lottery.
