Title: OctaMED glitchy after Picasso II install... HELP!!
Post by: Tension on June 15, 2011, 11:52:37 PM

Hi folks.

Long time no see!!

I've installed a Picasso II into my A4000.  Whenever I load my old MODs made before the gfx card were installed , they now sound wrong when played.

This can be cured by transposing the song by about 7 steps, and increasing the BPM by 2.5 times its original speed.

I'm sure there's a simple setting somewhere to sort this out, but I cant seem to find it.

Can anyone help??

Thanks in advance, and it's good to see you again. :)

Hmmm... I vaguely remember that there's some Picasso96 setting that's to do with addressing sound issues like that. The problem is to do with there not being a native screen open, which messes up the chipset timing from what I remember. Something in the monitor driver's tooltypes perhaps? God, I can't remember - I'm getting old! ;)

I think it has something to do with needing the FAKENATIVEMODES=NO tooltype in the monitor's driver?.

Cheers for the speedy reply.

Yea I havent used OctaMED or the Amiga in fact, for years now so I'm extremely rusty myself.

Cheers for the info, i'm off to google to check it out.

Anybody else got any ideas in the meantime??

I can't remember if the fakenative setting is it or not, but some Googling myself has produced mention of an env variable - ENV:Picasso96/AmigaVideo. It seems that setting this to different values changes the chipset timing. I'd have a look and see what you have in there...

Edit: According to the AHI documentation, this would normally be set to 31KHz to enable sample rates through Paula of 48KHz - I'd bet that's set on your machine!

I remember I would get weird sound glitches when I wrote Mods on the A1200 in DblNTSC screen modes and played them on different machines. It was a timing thing. Maybe the Goose can chime in here he is running Octamed with a Piccaso II on an A3000.

Just made some changes to the resolution in P96, now when I load OctaMED i get a black screen.

To be honest i'd relly need someone to talk me through it on a step by step basis as my Amiga knowledge has depleted at a most shocking rate.
