Implement Auto Envelope (SSG/AY) (Suggestion) about furnace HOT 9 CLOSED

from furnace.

mentioned it already, but good to have a separate issue for that. Auto envelope is crazy useful, allowing square/envelope masking and even ultrasonic EG (especially useful for AY8930)

from furnace.

Yeah, I agree. Setting the envelope pitch manually is painfully hard. Also, I did not know it was already mentioned.

Implemented for 0.4.6.

It doesn't work. On Famitracker, C-4 note with H9C (autoenvelope with shift of (9-8) and shape C (sth like sawtooth) produces a sound. Here, only a click can be hard with 29xy with same params. Envelope mode was set both in instrument settings and via 20xx effect. Freshly built from source

from furnace.

Effect 20xx does not set the envelope shape. Effect 22xy does.

from furnace.

it still does not produce sound, with or without these effects.

Try 2281 and 2911 at the same time.
Auto-envelope is implemented like this for greater flexibility:

• 22xy sets envelope shape and enable
• 29xy sets auto-envelope numerator and denominator

from furnace.

ah ok, it works. I have been confused by numerator/denominator terminilogy
