 Who remembers this freq converter?

Hi,

I'm in a need of a SID freq converter for our beloved plussy. I remember I found a nice freq converter eons ago but I can't remember the demo which used it. I know it used a freq table instead of calculating SID->TED note frequencies (used much less raster time) and simulated the ADSR volume changes. MConv1.6 does not fit for this case.

Who remembers this converter?

K.

AFAIR there were only three such routines providing some sort of volume wiggling -- ETC's, Coby's and mine (not counting several interim versions). ...And maybe one of Pigmy's late mconv routines.

Speaking of the code that does the calculation itself -- I remember basically four or five routines, of which three did make use of tables this or that way. I've seen the fastest one in some early '90s German production whose title I don't remember (must have been a Synergy megademo; ...Update: it was Disk Wars) -- fast, but not especially a precise one, sounded like hell. (Also, I don't remember this one using a routine that would have dealt with ADSR). The most popular one can be found in a lot of stuffs -- AFAIK even Coby's routines incorporated this calculator routine, you can even find this included to my pre-1.6 routines. ...Yet don't expect lightning fast operation, the table is not looked up but searched in a loop, which takes some time. And last, even mine (the last one, in v1.6) uses a short 128-byte table -- the algorithm is based on table lookups + shifts, which takes time. You can expect the latter two ones to be on pair by means of runtime; whilst, the first one is AFAIR faster than either of the latter ones but far less precise.

I can only remember solutions that stored the whole tune in a long row of datas that could be faster than these routines.

Az, egy "kissé" pontatlan.

Yea, it's sort of imprecise...

 Re: Who remembers this freq converter?

Dunno which kind of FRQ converter you're searching for, I can only list some:
Delta-Player
Fast Music Converter (probably the one from Synergy you were searching for...)
MConv V1.6 (love it so much!)
Relocator V1.6 (relocate Mconv V1.6)
TLCs Frq Converter Relocator V1.0 ((relocate Mconv V1.5?)
Music Converters (TLC's pack with Mconv 1.4 1.5 and digi)
Player Relocator V1.4+ (with CSM's Mega-FRQ V1.0)
TCL Music Converter V2.0+ (I added V1.0+ too in the same page)
TCL Music Converter 1551
TCL Music Converter 1551 (Chicken)
Muzax Packer

"I can only remember solutions that stored the whole tune in a long row of datas that could be faster than these routines."

For instance, the tune in Vector Victory is played this way. Really fast and not quite as RAM consuming as I thought

Luca:
About the TCL Music Converter: v1.0 is not the predecessor of v2.0 (the version numbering is indeed a bit confusing). It's the very same converter just for different memory locations. (v1.0 -> above $3200, v2.0 $0800-$4cff).

I think I should add this as a note

Thanx for feedbacks. I will check these utils soon I post a message of the result (which was I searched, etc.)

 Re: Who remembers this freq converter?

I found the old EDC site just a few minutes ago and at the bottom of this page http://www.szote.u-szeged.hu/neszt/plus4faq.html I saw a file named Converters.zip. There seems to be at least 30 music converters in the disk image in it. Maybe there is the one KiCHY is looking for.

Good! I'll examine the 3 packs in depth in the near future.
