maybe i don't know the right term, maybe it's not SMD but i found it in that category of the online store i usually shop and it looks like this:

all thanks go to bill who sacrificed his time and efforts for that cool project. i'll have a good time these days with my family and the SN VOICE PCB!!!
merry christmas espacially to all SN voice addictives and a happy new year.


FYI i corrected updated my eurorack frontpanel design posted earlier in this thread...

silly me! doesn't work! how could it? the NF version of the sn voice chip has a 0.07inch grid not 0.06! harrrrghh!

so i finally decided to purchase the appropriate high density DIP sockets from mouser! i want to be able to check the populated board but without the rather expensive SN76477 IC.
so if anybody in europe wants to join the order...
mouser part #575-693428

I should have picked that up since I had to make the skinny footprint in the EPCB library Wink

My first prototype with the production board, the one you have, was built using the skinny DIP package without any problems, thankfully Very Happy

Let us know how you do.

In fact, everyone that has built theirs, please post as a continuum of this thread so we can all enjoy the work each of us has done Very Happy

Then, maybe a thread containing SN Voice compositions !!! I will do one also. . I need to make new music as I have been busy with building, but, I love to compose also Very Happy

first up -
got my boards today - thanks Bill, they look very good.

2nd -
LF444s are hard to come by in Australia
plus i am a student so i prefer to use what i have in the cupboard.
So has anybody tried TL074s or TL084s, any probs or objections to doing so?
i remember reading somewhere the LF444s were chosen for their low power consumption.

Also i only have 1k tempcos, has anyone tried halving the values of the resistors on the input network in order to use a 1k tempco?

if nobody has tried these subs yet, no worries, guess i will, use sockets, try and report back

oh, this is my first post here. Greetings from Perth West Australia.
some of my toys are here -

If you only have 1K +3800ppm/C tempco resistors, you can series them up to create 2K. The temp coefficients do not add together, they will keep the same R-T relationship. Been selling thermistors for 20 years, so rest assured.

>The temp coefficients do not add together, they will keep the same R-T >relationship

that is a useful bit of info - cheers

i'm fairly sure the TL op-amps will be okay too
just thought it was worth asking

cheers

Andrew

welcome

I've been an admirer of Pinky for some time now! I'm trying to recall - did you have that in Japan for awhile?

IIRC, the LF444s were specifically chosen for the XR-VCO - TL0X devices did *not* work in that app. Had to do with the value of or lack of, a HF cancelling cap in the summer amp. Now, I can't recall if they worked any better in the SN-Voice or not, but that one does have a 1N cap there - so it just may work OK.

Cheers,
Scott

I'll bet this is the first SN76477 device used for drum-n-bass! Shocked
From Pinball machines to modern electronic !

I have the SN-Voice LFO set to about 5 HZ patched to the EXP FM with the attenuator set at 7 o-oclock. Pulse mode is selected with the output going to my new DIY VCA designed around the Analog Devices SSM2164 chip. My PAIA MIDI-CV GATE and 1V/Octave outputs are patched to the VCA CV-IN and SN-Voice respectively. My Korg EM-1 is driving the boat feeding MIDI to the PAIA unit. I created ear-popping snares with my EM-1 built in compressor and pitched the snares sound way up for a really classic d-n-b sound!!

I could have treated the SN-Voice with FX but wanted the raw sound from the synthesizer! The Korg and the SN Voice were mixed on my Behringer MX2642A and output was recorded to hard disk using Adobe Audition and Delta-44 audio interface.

Here is another short tune using the SN-Voice as the bass synthesizer. It sort of a Hard House affair !!

Hi Scott
>I've been an admirer of Pinky for some time now! I'm trying to recall - did >you have that in Japan for awhile?

correct, pinky was made in Japan. great place for getting into synths.
I was lucky enough to meet up with Motohiko Takeda and Houshu (Osamu Houshuyama), plus other synth diy crew in Japan.
they taught me a lot and showed me the best places to buy components in Akihabara (including one shop with heaps of SN76477s for 500Yen each(US$5))
one guy, Katzmi, did some good things with the SN chips -
http://analog-synth.jp/summit04/e_b_katzmi.html
(just some pics)
he liked his noise!

thanks, i will try them, but with sockets Smile

as long as the temco is in the feedback path of the inverting amp that mixes the incoming control voltages, we should easily be able to use a 1k tempco and divide the values of the resistors R33-R61 by 2 to maintain the ratio... that's exactly what ray did with his new improved VCO:

Here's my contribution for some raw, unedited and recorded on the fly, sound samples of the SN-Voice. It's how I like it!

The file is a compliation of short and a couple long jams. The controller is a 10 step baby sequencer CVing Noise/VCO and Gateing the EG.

That indeed would have been an awesome experience. Motohiko is one of my pals, though I've never met him. He makes some outrageously good rock. My SN76477 skinnies came from him straight from the Akhibahra!

Hey guys, love the SN-Voice recordings. Keep'em coming!

Here is a pic of my Dual SN Voice. Each one is 4U MOTM format, unfortuantly they arent up and running yet as I am waiting for the tempco's to arrive from Music From Outer Space. Each one includes the 3 mod's listed on Scott's site. So everybody pray with me that my MFOS order will arrive tomorrow.

The panel is 2 SN Voice's, Yusynths Dual Pulse Delay and MFOS Stereo Auto Panner / Leslie Simulator.

Beneath is my Dual Late MS20 VCF's.
