E.A.S. "miss10" HADSR PCB [SOLD OUT]

Post by E.A.S. » Thu Dec 22, 2011 9:55 pm

Hey guys,

Here is the next PCB to bring you closer to your miss10/20 build.

The HADSR pcb is a classic envelope generator circuit.

Hold, Attack, Decay, Sustain, Release!!!

In addition to the Standard ADSR it has a hold stage that can extend your gate time. (great for running it from pulse triggers) It also has on board, a unipolar output, a bipolar output, and an inverted bipolar output. All on a small 2.5 x 3.8" pcb (63.5mm x 96.52mm)

This board is the same size as the VCO, VCF/VCA, and the LFO/SAMPLE AND HOLD/NOISE pcbs.


They are High Quality Double sided ROHS compliant boards with
soldermask and white silk screen layer.

now included is a euro power connector. I've also added the MOTM style power connector.

On this board Ive also made provision on the board for different gate options. You can build it with and s-trigger input or a v-trigger input.

If you want in on this run, the price is $18.00 usd each, shipped anywhere.

payment via paypal to Michael (dot) alan (dot) schmidt (at gmail) (dot) com.

If you do not like supporting paypal I can also take credit cards directly through my business.

Two. Buy buy buy. Did I read correctly that you are taking payments now? For this and the lfo?

I guess it might be wise to wait a while after Xmas for payments to come in :lol: ...however Scrooge here has enough put away for 4 of these (and 4 of the LFO/Noise/S&H boards).

Cheers

excellent!
i'm in for a couple too. it's a good thing that you wait a few weeks, so i have some time to figure out how many i need (ie can afford)

Are you going to do the external signal processor from the ms20? That would be kick arse.

The impossible to get quad ganged reverse audio pots are used in 4 different sallen key filters. I wonder if an OTA could be used instead of the variable resistors so that a normal pot could be used to change the frequency.

I'm interested but would like to see the BOMs (rare parts?) before ordering HADSR & LFO/Noise/S&H boards.

How difficult would it be to add CV control over each stage?

I've been toying around with the idea of doing an ESP module pcb and have thought of the ota option as well. If I'm not mistaken it was talked about on the "miss 10" VCO thread. Its something I'm going to look into more.

Hi greg,

The original HADSR requires a shorting S-trigger type of gate to pull in input low. Ive kept the original circuit the same but added a simple transistor gate convertor circuit to the input. If you want to build the circuit for modular use, as I assume most people here will, this tiny circuit will keep this circuit a little more "standard".

If you want the original circuit just leave off the extra parts and add a jumper in their place. I'll document this more when the boards come in.
