Apparently this isn't the same as Infuzion's issue, so I'm starting a new thread.
The wavetable cannot play square waves. This isn't to do with Gibbs effect - Take a look at the output waveform in the picture below - I've also halved the output signal.
The problem gets progressively worse as squarer and squarer waves are used - this means that most waveforms are affected by this issue - and the unit is borderline unusable for me.
I've used the wavedraw OSC, but the issue affects anything using Wavetables.
See attatched OSM for further details.
I am using the latest version of SM, and would swear this is an introduced, 'new' issue. I cannot confirm this however, as this is the only version of SM on my computer ATM.

Something definitely looks strange there. I can confirm that it seems to work OK in 1.1.1beta1 (which happens to be the only old version I have on the PC I'm on at the moment).

The WaveTable prim seems to take only the first half of the array.

Only in some situations - in others it seems to take the whole waveform.

Yeah, its more than just that, looking at the screenshot you can see that its also screwing around with the DC in some way or another (no idea as to whether this is a root cause or side effect of route cause) - in the picture you can see that nearly nothing is at 0 in the drawn waveform, wheras on the output, the signal is nearly all 0 - DC adjustment is off as default in the wavedraw - interestingly, when I set the DC switch on the table component on the 'Table' primitive to true, the output goes from -0.5 to +0.5 ... suggesting that the fault lies at the point where the table is created, rather than where it is read. That is conjecture though.

out of curiosity i tried to build the simplest wavetable, but it does not give any sound at all, seems completely broken.
also while editing the above osm, synthmaker disappeared 2 times.

AARGH!!! MAJPR BUG! My KVR developer challenge entry is broken!
Thanks for the heads up Panoply.
@ Malc: is there a chance for a bugfix _this_ week! Otherwise I'll try to step back to an older version of SM!!!!
Nu Audio Science ·
Yeah same here RL hahahaha
Total nightmare
Thanks for spotting this one guys
NAS
MichaelBenjamin ·
so does my example give you any sound?
Panoply ·
Not a sausage - but then, the output from the table primitive consists entirely of 0.000000 !
MichaelBenjamin ·
no, its a square, scroll down 128 lines
MichaelBenjamin ·
ah i forgot square goes -1/1 but anyway atleast it should play something.
Panoply ·
the output from the resample is - ::edit:: its still a square, just a unipolar instead of a bipolar one. 🙂
the output from the table is just 0.000000 the whole way through - whatever I switch the average to. 🙂
Or have I misunderstood? 🙂

It propably was a change in the last minute. In 1.1.3RC1 it doesn't happen, too
MichaelBenjamin ·
yes, the wavetable seems totally broken, just after i changed the array to -1/1 synthmaker disappeared.
kirkagur ·
I Just changed the Midi to Ploy to 0-1 from Hz and it worked.... 🙂
Edit: Ahh... Sorry I had the 1.1.3 beta open.
malc ·
Apologies all. Indeed it was a last minute change (will I ever learn?!!!). I was trying to correct another issue and it's had this knock on effect.
A big problem caused by a tiny change.
Fix will be up very soon.
malc ·
Fix available - details in the testing forum.
rl ·
Thanks for the quick fix. It cured my problem!
Panoply ·
Yes, this is working great again, thanks Malc 🙂
malc ·
Excellent!

aye, but that was uttered in a mood like my ships have been sunk by the spanish armada 5 minutes before (and misspelled in panic as you see), a mood NAS' avatar has somewhere in the middle of the animation (before the 1st eye gets off)
