aa45142728 Endeavours to fix attenuation and add FM synthesis.
I now definitely think my frequency counting is wrong.

09d1aed3a5 Attempts to voice the current attenuation (and, therefore, the ADSR output), even if linearly rather than logarithmically. 2020-04-13 22:12:55 -04:00

a1f80b5142 Takes a stab at per-operator ADSR.
Heavy caveats apply: no KSR is applied, non-ADSR attenuation isn't applied, attenuation isn't voiced in general.

cb1970ebab Switch to more compact form of output for bool.
This also will hopefully deal with GCC's slightly confused claim that 'value' may be used without having been initialised down at #define OutputIntC (i.e. after it's out of scope, but I can sort of see why GCC might get confused while it remains in scope).

632d797c9d Adjusts frequency formula. This could be close.
I guess next I need to get ADSR/volume in general working, before I can go FM? Then I'll worry about using the proper log-sin/exp tables.

dd6769bfbc Splits OPLL and OPL2 classes.
Logic is: they have different mixers (additive in the OPL2, time-division multiplexing in the OPLL) as well as different register sets. So I'll put operator and channel logic directly into those structs.

Merge pull request from TomHarte/6502Tidy
Makes `State`, and therefore the 'Reflection' dependency, an optional adjunct to the 6502.

e4d4e4e002 Adds 6502 State to the SConstruct file.
On the assumption I'll actually use it at some point.

f417fa82a4 Splits 'CRTMachine' into three parts: ScanProducer, AudioProducer, TimedMachine.
Simultaneously cleans up some of the naming conventions and tries to make things a bit more template-compatible.

cfb75b58ca Pulls all 6502 MicroOp sequences into the main operations_ table.
This will make state restoration somewhat more tractable.

4fbe983527 Provisionally adds State and get_state to the 6502.
`set_state` may be a little more complicated, requiring a way to advance in single-cycle steps **without applying bus accesses**.

2320b5c1fe Takes some steps towards five-and-three decoding.
Now I 'just' need to figure out how bits are distributed within the decoded sector. The XORing and data checksum seem the same (?)
