Stupid Hardrestart...

A question to all msx-player coders.

Why 99% of all players have a completely worse hardrestart???
I only know a few (not more than 5) which owns a really HARD = good sound-restart.
With every other player it's impossible to create modern/up-to-date instruments.

I think there are some nice editors (with nice interfaces) out there, but the completely outdated hardrestart destroys everything. :(

So, any explanation for this?

Now let's come back to topic ...

Let's say a certain player/editor has a quite "OK" hardrestart, but is slightly inaccurate on the first waveform after the $09. (F.ex it extremely bugs if you play several notes consecutively...)

09 00
51 AA ; always starts slightly inaccurate
11 AA
11 A5
10 A0
10 98
10 90
10 81
FF 10

What can be done to solve this problem? It's possible to hack (no player source available)

Maybe someone could help?

Hacking is always an option. :D

Possible nonhacking option: maybe create another version of instrument where gateoff starts earlier? (or manually gate from the pattern)

Btw. you can name the player/editor. That way it's more educational for everyone.

Hmm, I saw the player code doing a
lda #$00
sta $d404,x
sta $d405,x
sta $d406,x

This is usually meant to be done only 1 frame before note init, because it cuts out sound completely in addition to hardrestart. The same as in ninjatracker - it won't accomplish a reliable "hifi" HR. Major hacking would be in order.

Btw. there IS the player source as a turboassembler file on the second disk.

Actually, I might have been talking out of my ass, that code snippet above doesn't seem to appear in the actual player source code. Though, the source code suggests on a cursory glance that there is no automatic HR at all :)

I think it's possible to set a "gate" value for each instrument.

Anyway, it's possible to 'hack'??
