Hi all again smile,

It seems that defmon uses slightly different frequency values to the first principles calculations at http://codebase64.org/doku.php?id=base: … ncy_table.

Using the latest defmon (20181101) under vice, setting sound device to "dump", I see that sending a defmon A6, results in hi 29/lo 71 (0x1d47) being set in the voice's frequency registers.

By contrast, http://codebase64.org/doku.php?id=base: … ency_table says A6 (they call it A5) should use 0x1d46. Though the calculation given in http://codebase64.org/doku.php?id=base: … ency_table says 0x1d45!

I'll set up my Tek scope to verify - but which of these 3 values is correct? smile I presume defmon is...

Thanks,

Hi all,

Noticed what I think is a filter control corner case - defmon doesn't seem to touch $d415 (54293)/register 21 - filter offset low.

If I run the latest defmon (20181101) under vice, set the sound device to "dump" (ie. so I can see what register/values are being written) and either set an absolute value under ACID or a sweep value, I only see register 22 being set (the high offset). Likewise setting CP only seems to affect register 22.

Is this intentional? It does seem then that the rightmost 2 ACID digits don't do anything.

Thanks,

Hi all;

https://vimeo.com/295475988

I made a very simple defMON introduction,

I'd very much like your feedback - my goal for this video is to make it easier for people like me to get started and get over the initial terror smile. It'd be great to work with others to have other tutorials on things like hard restart, understanding how BPM works, more advanced effects in the sidtab, etc.

Thanks,

Thank you very much. Another kind soul also just explained that to me privately.

I'm doing a basic video tutorial at the moment which I'll send in a couple of days for review (also been digesting all the helpful background in this forum). If anyone here has time to review it (especially for accuracy) that'd be great. If I get the basics right then perhaps it might support a bunch of different follow up ones that concentrate on various sidtab techniques.

Hello all,

I have am embarrassing n00b question (thanks for defMON BTW - having a great time learning it). I'm using defMON 20171026.

Using the seqED, when I edit anything for voc 1, my edits are immediately mirrored to voc 2. In other words, if I add a C4 to voc 1 at some step a C4 immediately appears in voc 2 in the same step - and goes away when I delete it from voc 1. Likewise with sidCalls etc. I'm sure I am not in super command mode. I've loaded some patterns written by others and edited them and the mirroring doesn't happen, so I feel it must be something configurable/stored in the workfile.

I can't for the life of me figure out how to disable this mirrored editing. I feel like this may be a n00b test to overcome, in which case I clearly am failing it. smile What's the secret?

Thanks,
