I started an open source project: fseq-flash is a formant sequence editor. Current features include:
- Import AIFF files
- Audition and edit formant sequences in real time
- Vowel- and function-drawing tools
- Export .syx files for the Yamaha FS1R
You can push your formant sequence to the Yamaha FS1R, using software such as K_Take’s FS1R Editor. Click the “Save .syx” button, and follow the instructions in K_Take’s documentation. This is a lot of fun, and breathes new life into the FS1R.
This project became much deeper than anticipated! The code includes FFT analysis (thanks Gerry Beauregard), pitch detection, a formant detection algorithm, and an AIFF parser to read AIFF files. The interface was a challenge to design and implement, and there are still many unfinished features.
My energy is shifting to other work, so I’ll enhance fseq-flash when time permits.
