QSound and Assembly

[spkr]

Hi there,

I recently obtained a QSound device, and now that I cobbled together a working oqtadrive, I *should* be able to get my own programs running on the QL using the QSound! However, currently that is not yet the case.

I was wondering if anyone went this way, or got some suggestions for me to try out. So far I tried to play one of the predetermined sounds:

Following https://dilwyn.qlforum.co.uk/docs/manua ... QPRINT.pdf :

Code: Select all

    moveq    #0,d0                  
    trap    #1                        ; MT INF
    move.l    $164(a0),d0                ; get $164 offsert from system vars, which is the AY.JMP (page 9)
    move.l    d0,a0                    ; use AY.JMP as address

    moveq    #9,d0                    ; play predefined noise (page 19)
    moveq    #1,d1                    ; play predefied noise (gunshot)
    jsr        (a0)                    ; jump into the thing (similar to page 8)

However this not yet yield sound. (I Confirmed the QSound working by using the basic command, which works).

Later today I will try and push raw data to the registers using the AY.WRALL; but Ideally Id like a really minimal example as a proof of concept that I can make the QSound make sound from assemble.

Any input is greatly appreciated; I hope to get some music going for my upcoming Sinclair QL intro

Kind regards,
Wietze

Quick followup; it seemed that setting individual AY regs using trap calls did work.

So I used this and that worked like a charm.

Kind regards,

Hi Wietze,

Truely excellent, I have been struggling with this for a long time.

I will have a play with the Qsound boards I have like writing in assembley language.

Hi guys,

I've released a little prod using the qsound. It can be found here: https://www.pouet.net/prod.php?which=95891

It also contains a YouTube link in case you do not own a qsound.

Kind regards
Wietze
