Samar crew is proud and happy to announce brand new '$11 Music Compo'. Figure out how much you can do with your hands tied 😉 It's all about sheer fun!


Compo rules:

- only triangle wave, no wave or testbit allowed
- no ringmod or sync
- single/multispeed allowed
- no digis (thcm digis use only $11, $01 and $09 but... no)
- 1SID only
- min. 2 minutes playtime
- any number of tunes per musician
- tunes can be submitted till the end of 02.03
- please supply executable first and then sid, otherwise CSDb mods will skin you alive xD
- other necessary rules might be added later on


Voting:

- there's one week after compo deadline to vote
- CSDb is voting platform

Since there's already some limitations in place, how about restricting the size of the binary to 2KB (for example $1000-$17ff). This might result in new code.

... and less entries :)

What do you mean by no wave?

If your editor of choice gives you that option, you can set wave register to gate on or off ($01/$00) without any waveform selected. It works practically as testbit - sound stops abruptly, just waveform phase is not resetted. Goat Tracker doesn't allow to put such value directly into wavetable (everything below $10 there is mapped as step delay) but you can still make use of 701 command in particular track which results in the above :)

Oh.. I first read it to be "no ... testbit" allowed, but now I see how you mean. So basically any combination of bit0 (gate on/off), bit3 (testbit on/off) and bit4 (triangle wave on/off) is allowed in that register, whereas the other bits must always be set to 0, right?

That would limit choice of editors surely. Goat Tracker player is modular hence it would compile smaller player but I'm not sure about other editors. Compo is musicians' oriented and rule set is already quite demanding ;)

Exactly :) Just to give you a little hint in Goat Tracker - as it doesn't map values $00-$0f directly into wave register, you can still use e.g. $e9 to trigger testbit in wavetable. Cadaver's little workaround :D

edit:

Actually I was wrong about very gatebit as you can still write $e1 into Goat Tracker wavetable. (Me ducks and covers in shame :D)

As this particular rule seems confusing gramatically:

- only triangle wave, no wave or testbit allowed

Let me rewrite it with Oxford comma:

- only triangle wave, no wave selected, and testbit are allowed

I hope it's not that confusing now ;) Frantic did explain it the best anyway ;)

to me now the 2nd way seem to be contradicting the 1st.
is test bit allowed or not?
Seems more a coding compo than a music compo to me, but what the fuck I know, good luck =)

Well, in music editor you program wave register too ;) It's legit music compo - not much coding here, unless you create your own player.

You can manipulate triangle bit, test bit and gate bit. I didn't want to put it that way initially to avoid confusion among musicians without programming skills but it turned out English is a bitch xD

- triangle waveform
- no waveform
- testbit

That's more or less what twisted grammar was supposed to convey ;) Sorry! :D
