Agreed Andy

I earned My living as a working musician all My Adult life Yet I have never come across anything as hard as this

A simple three channel bleep and and hiss chip, yet the beautiful music created by the likes of Yerzmyey, sergey, Agent x ,Gasman, etc make Me want to salute Them all as really gifted musicians equal to any in My old school world

Like You Andy I'm having to start off with something simple but bit by bit I think we will get there.

All we need now is Charlie to say He's not bothering with the boards but designing a new rampack instead

Ooops i thought i broke it...

but no, i was trying to load 15K long PT3 file into an 8K memory space

now who is the dumb dumb

Andy

p.s i feel i slight revision comming along, player inside rem statment too.

[Moggy]

Sounds good

Just a thought, but bearing in mind the 32K RAM available on the ZXPand, could the AY files be placed in the top 16K of memory, thus allowing full 16K games to be used at the same time?

yes Rich thats exactly what I'm, working on at the moment, 16-48K ramspace, interrupt handler and player in REM statement, and ny lowering RAMTOP further down to 26500, i'm able to load all 8 of the SHOCk files into ram at the same time, of course you can still only play one at a time

P.s. however you can't put the handler above 32K you can't execute code there without the M1not modification.

That is what I feared - don't yyou say the handler itself is some 8.5K ?

Would it be possible to maybe chain in some of the handler as and when required, so that only the code being executed is actually using up the standard memory?

That said - surely most software is written for a maximum of 16K - so the handler could be placed in 16K-32K or am I misinterpreting your comments?

[Andy Rea]

the player which i have currently loaded at 8192 is 2245 byte (it's been tweaked a bit since mod6) the interrupt handler in a rem statment is just 97 bytes

i guess you could put both at the top of ram 32768 - 2245 - 97 = ramtop of 30426.

That leaves a fair space for programs, but realistically you would only want music with programs fully in MC as it uses up around 1/4 to 1/3 of available processor time, whilsy running in SLOW mode.

Steady on Andy I can't keep up
An stc player and a pt3 player in less than two/three weeks

You are certainly putting in the hours Andy, more power to Your elbow Sir

A big "thank you" for these developments. Hardware is nothing without software.

Hi Bruno, i guess that sample tracker playback would be possible, of course there would be no option to keep a active display on ZX81 during playback, it would just not be possible since as sample tracker needs near real time data sent out to the AY chip.

Once I'm done / bored with the 'normal' tracker stuff I'll have a look see what i can do.
