I have build a vocoder based on two Behringer 914 filterbanks, 14 envelope followers and two Doepfer eight channel VCAs (of which I use 14), but haven’t come round to writing about it because the circuit is quite complex. Complex in the sense that it contains quite a few modules to realize it and explaining what they all do and how they need to be interconnected is quite a task. Furthermore I want to make some music with it first so that I can include it in the write up. After using the hardware vocoder for a while I found that the attack pot of the envelope follower did not bring much and in a next rendition of the device could best be left out. The remaining part of the enveloper follower however suits its purpose and you probably do not need the more refined [Follow-O-Matic](https://lookmumnocomputer.discourse.group/t/envelope-o-matic-v0-2-aka-follow-o-matic/3171). As you may know I created [Vocode-O-Matic (D31) for Daisy Seed](https://lookmumnocomputer.discourse.group/t/vocode-o-matic-d31-for-daisy-seed-a-31-terts-band-vocoder/1936) which has 31 filter bands and a very flexible modulation matrix / patch matrix. This version sounds **soooooo** much better than the hardware version, and is **soooooo** much more flexible in its configuration, that it is more worth my while to invest some more time in making that into a module than to write about the hardware version. But if there are any specific questions, I’m happy to answer those. --- _[View the full topic](https://lookmumnocomputer.discourse.group/t/envelope-followers/2938)._
