PS. Does this tracker support samples as it is a wavetable edition?
32 byte waveforms are samples 
But no the tracker does not enable sample playback longer than those.
I'll put you on the tester list for the next distribution. (might take a couple of days).
And what about supporting 2 SCC's at the same time? (2 x 5 channels) 
Anyone got any tips for the instrument editor? I thought I'd try the easy way and copy a bassdrum from some vortex tracker songs, but it didnt work, didnt sounded anything like the vortex tracker version
It's hard to tell when I'm not seeing/hearing it. But first:
* check if the step on which it 'loops' (marked by the 'R') is still correct. It may have shifted a step
* you may have to rework some frequency offsets; look if the offset returns to 'normal' (000). Remember that, unlike VT, here all stated values are relatives instead of absolutes
* note that a substantial part of the sound you're trying to get just may rely on HW envelopes. TT doesn't support those. If the 'E' is highlighted in the VT sample (macro), it's calling envelope commands
I forgot to say - are you on the e-mail list of beta testers? Then don't be shy and just mail *everyone* with your question(s).
Among the beta testers are brilliant guys like [WYZ] and Gryzor87, and there's also me, so just ask, and I'm positive that there's someone that'll be happy to help you out.
Do you have the
MBM_CONV.IS
file on the version you're working on?
If you load that instrument set, then starting from H, there are some ready-made PSG drums as well.
