The two files for you to check.

Moggy.

Yes I grasp it now Charlie but all I'm after (quite selfishly I know ) is an emulator that can load the tracker, create samples and songs, save them and have a good AY implementation. Up to press only Olofsons emulator does some of this. The AY emulation is spot on, the tracker loads nicely but when...

Many thanks Cesar much appreciated.

And the example you give is exactly what happens with Olofson's emulator which has no Xpand support.

Are you making fun of me Charles!!!!

I tend to agree with your final statement as the Xpand seems to mimic the Spectrums "SAVE CODE XXXXX,NNNN" function so yes when the tracker saves a "song" file it is indeed saving a block of m/code from a certain memory area to the xpand just like a spectrum data save which is how spectrum based tra...

Yes Andy ramtop lowered as needed but it is in Olofsons emulator not Cesars where it crashes( not tried it in his yet). To be honest that's not really a worry for me personally as long as I can save tracker songs on PC and transfer to real thing. the tracker works superbly in his emulator but unfort...

@ Cesar. Olofson is working on his own emulator and has asked me to try his AY implementation. The tracker works great when playing, with correct frequency etc (but I have not tried it for composing yet) and so does the player so not broken after all maybe? Perhaps a word with him could help you sol...

Hmmm just tried the player you mentioned and after loading and running, the emulator just automatically calls the xpand "CAT" command. IE a list of files in the directory that can be loaded. Many thanks for taking time and trouble with this Cesar and one last thing although not a great worry the AY ...

Hi Cesar.

Tried Xpand emulation as you suggest and Yaaay files now load but after about 10 20 secs of song play screen corrupts badly then crashes.

No, but 1984 was when the QL went on sale. So I suspect that the ZX81's that were still being sold were the last of a batch that had been made in 1983. The ZX Spectrum became the priority soon after launch when it became clear that it was very popular. Sales of the Zeddy slowed from then on. Mark I...
