I just wanted to mention this stereo SID unit:

http://www.sidfx.dk

The reason is that I think that project deserves all the support it can get. I'd say it is the ultimate stereo sid solution. At least as "ultimate" as it gets in actual practice. Among other things it allows you to put any SID model(s) in any C64 (such as new SID on old breadbin, or one of each SID model, or whatever). Perhaps I should also say that I am not affiliated to that project, but merely a customer. It might only be produced in one batch, so if you want it, this is your chance.

It works with defMON, and when and IF defMON 2 becomes reality, it will certainly support this thing too, including the special features.

DefMon looks powerful, but has almost no documentation.

Yep, not that much documentation. Just wanted to point out that the little documentation there is, is available at:

In most cases C64 Players execute once each screen update, so some standard C64 speeds are:

2 = 187.96703296703296 BPM
3 = 125.31135531135531 BPM
4 = 93.98351648351648 BPM
5 = 75.18681318681318 BPM

As Ilkke says, defMON allows you to set speed in a much more finegrained way that this. Nevertheless, you might still not hit exact "integer" BPMs like "125" etc. For example, by setting the timer interrupt value of the C64 in defMON to $4cf8 and using speed 3, you'll get 124.9997462572951 BPM, which is quite close to 125 BPM, but not exactly 125 BPM.

On the other hand, you can use Scannerboy's sync interface to make all your synths and gameboys and whatever obey the speed of the C64 running defMON. wink

d3NI$e: Sounds a bit like a flakey keyboard to me. Anyway, if it was indeed something that went wrong with the keyboard reading code, then you can always try pressing SHIFT+X to get into the disk menu. Reason: When going to the disk menu there are a bunch of things under the hood which are resetted/restored, so going to the disk menu and then back to the editor might help. Then again, you said the only thing that worked was going into the sidtab, so I'm not sure if going to the disk menu would have been possible, but anyway... smile

By the way.. Just came to think of something which may be relevant in relation to the question of playing something over and over again. If you press F3 to "PLAY FROM HERE" and then press F7, it will stop where you are, but if you then press F7 one more time, the editor will take you back to where you started playing from. Then you can press F3 again to play the same part of the song again. Not exactly what denize asked for, but at least a bit related to that.

No need to press CTRL for voice muting as far as I can remember. (In fact, those voice muting keys work like "shift/ctrl/C= keys" in the sense that you can press several of them at once without having they keyboard handler getting confused, meaning that it doesn't actually matter if CTRL is pressed at the same time or not, since these three voice mute keys are interpreted separately anyway.)

Use F8 in the RE column to set resonance to F and "turn filter on for current voice". (You can also hard code which voice that should be enabled, although that is rarely meaningful/useful: F1 would enable filter in voice 1, F2 in voice 2 and F4 in voice 3. So F8 is a special function used by the editor, meaning that it figures out internally how to set the SID depending on from which of the voices the sidtab chunk was called.)

Hi! To be honest I don't quite understand the question. The "three times X and then Y" sounds a bit like the looping function where you play a particular segment X times before proceeding to Y. On the other hand, there seems to be other things involved as well, which makes it somewhat hard to grasp what exactly you were doing and what exactly that happened. In general there are no known bugs that remind me of any of this.

As for your other questions: No there is actually no way to loop current song position just by pressing a key. You have to put FFXX00 in the sequence list in the step after, so e.g. FF0200 would jump to position 02 in the seqlist.

As for how to edit tunes in the editor while playing the song... Just press play (F1 or F3) and then edit all you like. You may want to toggle "followplay mode" on/off by pressing F5 so that the sequences are not scrolling while the tune is playing.

Some birds can fly.

There are several tools that allows conversion from executable C64 files (e.g. packed sid tunes) to playsid format (e.g. with the header that ilkke mentions). Since I never use them myself I don't really know what to recommend, but here is one, assuming that you're running Windows:
https://csdb.dk/release/?id=6600

Here is yet another one, also windows executable:

The actual format of the playsid header that ilkke mentions is documented here by the way:

Even in Goat Tracker ntsc is slightly higher pitched than pal. it kind of bothers me. actually it really bothers me! Why does Goat Tracker gotta do that??

This is actually what happens per default if you use the same frequency table as you use for PAL. The same SID settings come out more high pitched on NTSC machines than on PAL machines. So, in essence: In order to have the "same" frequencies coming out in the speakers when using PAL and NTSC machines, you need to use different frequency tables. So it is rather a matter of what GoatTracker is not doing than what it is "doing".

There is an explanation how the sync interface works from within defMON in the "WHAT'S NEW?" section on this page:

I don't have very much to add to the discussion other than just confirming that those SD thingies should work fine with defMON at least. Most likely with sidwizard as well.
