by stopping the OSCs? i've made a simple patchin pd (pure data) for this - if no note is played then OSC1/2/3 is set to i think 16 (off) but then the patch must have the OSCs set to what they need to be in the wavetable. still it's useful. but if this was implemented in the application it could just automatically set OSCs back to what they're set in the patch when a note is played and the OSCs are stopped (to minimize popping artifacts). i searched the forum and the only reply of yours i found was somehting along the lines that it's a unique SID "feature" and that it would be a shame to work around it... well the thing is that the triangle waveform has this really annoying high-pitched leaking that makes it useless for a "suboscillator" (but as a waveform with very little higher harmonics -almost sinus - it would be very appropriate). even if routed through the LPF the beeping noise is still annoyingly loud. would that involve alot of extra code? i imagine not... if you think it's a good idea i might take a look at the code and try it myself... maybe only if you gave me a general pointer to what section it would be best put into. how are others dealing with this issue? maybe any simple workarounds/fixes i didn't think of? (besides gating the entire signal)

i'm wondering. i need an analogue delay and need to decide between Dynacord Drs-78 and Yamaha E1005. the dynacord is a bit more expensive but it also comes with a reverb. but it's possible that the delay circuit is analogue (BBD). the reverb is most definately not spring reverb and the entire unit says "DIGITAL reverberation system". the only reviewer on harmony-central says the delay is BBD but other places on the web say 12bit digital... i'm confused. yamaha is analogue for sure. i'll probably get both of them tomorrow for testing and will have the chance to open them. what to look for in the dynacord (in terms of BBD ICs)? any of you guys have any experience with any of these 2 machines?

yep that would be sweet.

just a second... if your encoder really is 18 detents then 4x18 = 72 and that means it's okay it's quadropled.

fuck

you mean it's like... really old? :-[

i got about 7 SIDs and all were socketed

why not? :-\

from http://www.visualsound.net/bbd.htm prices: MN3207 - 1024 stage low-voltage BBD: 1-49: $3.75 50-250: $2.75 251-999: $1.75 MN3102 - CMOS clock driver for low-voltage BBD chips: 1-49: $1.95 50-250: $1.75 251-999: $1.55 this is good news huh guys? anyone has any good delay schematics that utilize these panasonic BBDs?

ah okay :) i won't do it.

great! i'll see what i can come up with and post here.

hmm okay i guess i can try... do i need to increase or decrease the capacity to lower the center frequency? change it how much? have you maybe already tried any other values?

hey i just thought of something - regarding the 8580's funny filter curve: now i know that the problem (the steppiness) is in low filter controller resolution in the low frequencies range. maybe it hasn't been stated like that yet but i think it sums it up sufficiently. AFAIK there's alot of headroom left in the higher freq range (up till the max freq). so - i remember reading about how different filter capacitors for the SIDs result in different filter range. now - i don't remember exactly how capacity affects the filter frequency range but - the big question: would it be possible to pick different filter capacitors so that the range would change (shift downwards) sufficiently to raise the controller values so we wouldn't have to use the "steppy" ones? it would probably mean that we'd also have to change the mapping table bu maybe different capacitors would also change the frequency curve? has anyone maybe already experimented with this? TK i'm really sorry if i'm poking at this unpleasant topic again - it will probably turn out (again) that i'm not getting something right and i'll apologize sinceirly and hope everything will be well :-*

well so it's possible. the polystrene caps... i can't get them at my local shop so i'd have to order them :/ hmm 122$ for the components. it really isn't THAT too much.

hehe that's great. what do you think about the pixie? too bad mouser doesn't ship to slovenia :-\

:) okay, thanks. but what did you have in mind (burning down the house)?

http://www.paia.com it's a sad year for synth scene... rest in peace :''(

ah so the pixie isn't for sale yet? thanks a lot for shedding light for me on this thing. i guess i'll go with the pixie ;D

i didn't mean to bash on Laurie. i was just wondering if it's worth the money. you guys posted exactly what i needed (and on some other forums that i posted this question on). i guess i'll order something and see. probably i'll go with the pixie... the simplesizer clone is simpler but i think i'd manage the pixie. can i ask you guys - is any of these ICs hard to get: Germanium Diode 1N4001 50V 1A Diode 1N4148 Signal Diode 6N138 - Opto-coupler +5V 1A Regulator +9V 1A Regulator CA3080 - Transconductance Opamp CD4007 - CMOS Logic CD4011 - CMOS Logic CD4013 - Dual D-type flip flop CD4015 CD4016 - Quad Analogue switch CD4024 - 7-stage Binary Counter CD4030 CD4051 - Single 8-channel Multiplexer CD4069 - Hex Inverter Unbuffered CD4081 5V0 Reference Diode LM386 - Opamp LM3900 - Quad Norton Amplifier TL081 JFET Opamp 2N3904 NPN Transistor 2N3906 PNP Transistor 16MHz Crystal thanks for all the replies. i didn't mean to be rude. sorry Laurie if you're reading this - i just needed some opinions :)

nah i'm mostly interested in the pixie and the asm-2. i'm not too keen on seeking out each component piece-by-piece... at least not at the moment with the knowledge i have. i would have bought just the PCBs and wait with them a few years but even just the PCBs are too expensive just to put them in the drawer :/ the schematics... they don't have any of the PCB layouts... or am i missing something? also... now that i'm looking at it again... funny that they decided to put everything on one board (speaking about pixie and asm-2)... they could have made 2 or even 3 boards and give people more options for enclosing. the single PCBs are pretty huge from what i've seen.

still - what do you think about the prices?

not the prices i listed. there's a link on that page to pick the currency.

http://www.elby-designs.com/ any of you guys have any experience with them? the wasp clone - "pixie" - looks mighty fine but 124$ seems a bit much for a PCB... and then additional 122$ for the PCB component kit... that's almost 250$ just to complete the PCB. and apparently you HAVE to buy the instructions CD for like 7$ if you want to assemble it. again, the synth really looks powerful but i think it's not cheap. then the ASM-2. on the "official" ASM-1 page it says that elby is now selling the boards. but elby doesn't seem to be selling the ASM-1 PCB. instead they made the "ASM-2" (which, again, looks fantastic) but - it all looks kinda fishy to me. don't get me wrong - i think it's awesome that someone is putting these out and still it's probably small money for what you get. and i'll probably end up buying something from them. i'm just looking for some more info and possible user feedback. anyone knows any forum or something that has some feedback on elby?

maybe it would be cool to have an octave shift for every row? velocity: AFAIK the cheap midi keyboards do this by measuring the time delay between 2 points of the vertical position of the key.

oops "anything" ;D but - is "something" really totally wrong word here? i mean... is there no way you could use that maybe like on the street?
