SMR-4, MIDIpal in video soundtrack

Jon — Fri, 18 May 2012 07:32:07 +0200

Here's a short video recorded in the British Columbia interior with a soundtrack featuring the SMR-4, MIDIpal and Monotribe: http://www.youtube.com/watch?v=4JZApsYzdhU

Sorry quick question. Do you cut the bottom?

Shruthi XT programmer, knobs and leds and assembly questions

rumpelfilter — Tue, 15 May 2012 12:51:35 +0200

I’m now a proud owner of a Shruthi XT kit from FCD72, but there’s a couple of customizations I’d like to make to the standard set of things that come with the kit.
First of all, I’m a bit of a knob fetishist, meaning that I don’t like rubbery plastic knobs, and rather have the something more old-school. The problem is, as Frank has explained, that the pot shafts are a bit too high for most pots and hence need to be dremeld down a bit.
Since I don’t have a dremel, nor a workshop where I can perform such an operation, and my wide already hates me enough for soldering in our living room (which is one with our kitchen, our studio and our library) I’d rather not do that.
Does anyone know some good 6mm shaft knobs that look something like these:
http://www.musikding.de/Knobs/Knobs-Plastics/Metal/Black-Fluted-Silver-Center-20mm::161.html
that work with the shafts, so that I don’t have to dremel them?

Question nr.2: I’ll have to de-solder the leds on the Shruthi, since they have been soldered for the transparent case, but the programmer frontplate is opaque (with the holes). I need to raise the leds a bit to stick out into the holes. Since I always made a big mess when de-soldering leds, do you have any special tip on how to do this?

I’m not in a hurry a friend of mine will do most of the assembly job, and neither I nor he have the time to get to it right now… but I can start sourcing the remaining parts and plan the thing properly :)

BOM for mouser

Nedavine — Fri, 18 May 2012 09:27:34 +0200

I'd like to use mouser.co.jp (as I'm in japan) but i can't seems to actually download the BOM from the site and the mom links are for the french mouser. is there an easy way to do this? is this an amazingly glaringly obvious problem? heheh
cheers guys

Control a Shruthi with a Theremin?

Mr53rg10 — Mon, 14 May 2012 02:51:36 +0200

Hi!

I saw that Moog makes a new theremin with CV out. THey say it is possible to control a synth like that.
Well, I see that Shruthi has got CV in.... What do you think?

The only problem is that the etherwave plus is TOO expensive.
But I like to dream in advance :)

Thinking back on how she met up with Moroder and brought some true innovation to music as we know it today. Just by chance I listened to I Feel Love not too long ago and thought to myself: “This sounds modern even in this day and age”!

Respect!

Power 3 Shruthis from a single PSU ?

hpsounds — Thu, 17 May 2012 21:22:15 +0200

Sorry for my lack in electronic design. I’m wondering if and how can I power my 3 Shruthis with a single PSU (mine are rated with 9V – 1100 mA) from which run 3 cables plugged in each Shruthi ?

Thanks for your help !

Mutable Cuisine - Recipe of the Day for the uninspired Chef

fcd72 — Sat, 31 Mar 2012 18:53:37 +0200

Recipe of the Day: Bread with Onions + Nutmeg and Butter with Herbs, Chili, Garlic, Lime Zest and coarse Sea Salt

For the Bread mix approx 200g wheat flour (Type 405) 200g wholemeal wheat flour and a bit of rye wholemeal flour, add a spoon of salt, a spoon of sugar, loads of fresh grinded Nutmeg, dissolve a piece (42g its here n Germany) Bakers yeast in approx 500ml of cold water and and work everything to a nicely dough. Get a Kenwood if you are lazy. Add a pack of “roasted Onions”:http://sv.wikipedia.org/wiki/Rostad_lök and knead again. Let sit for about an hour and reknead. Put a bowl with water into your oven and heat it to 225°C (not in the hurricane Mode…). Form you bread, put on a pice of Baking Paper and bake for about 45 Minutes at 225°, then lower the temperature to 160° for another 30 Minutes.
For a an excerpt on hot to make Bread properly read Locatellis Made in Italy (if you only have one book about cooking this is it!)

For the Butter take a pice of soft fresh (irish) Butter and mix with Herbs to your like, finely chopped Chilis, Zest from 2-3 Limes, and Gralic thats been crushed together with the coarse Sea Salt.

Beginner Guide to Shruthi alternative control.

Silverfish — Thu, 17 May 2012 08:44:57 +0200

Hey team-

I haven't gotten an enclosure on my SMR4mkII Shruthi yet, because I'd really like to add a few things. You know, stuff like in/out volume knobs, 2/4pole switch, bandpass switch, FM input mod, and maybe some CV in/out. It's the CV in/out that I'm most unsure of.

Here's what I get:
The IN1>-IN4> can accept 0V to +5V.
The INs cannot control pitch value.
The CV1< and CV2< are connected to the Filter Board but go nowhere.

Here's where I ask dumb questions or say stupid things and you guys get to school me:
I would like to have 4 CV IN jacks. The jacks connect to IN>1-IN>4, respectively, and GND. What about +5V? When is that applicable?
I would like to have 2 CV OUT jacks. Can I just connect to the pins poking out the bottom of the filter board?
For the extra CV IN FM mod, it says to add resistors. Pretty clear. Can you just feed the pin an input signal? What's the difference between sending a CV signal and an audio signal? Internal audio?
What "protection" do I need on the CV INs?

Okay... I think that's all of my questions. I realize it's a lot, and I'm in the deep end of the pool. Thanks for your help!

DIY midi controller. Suggestions?

jazzdoktorn — Thu, 03 May 2012 19:15:04 +0200

Hello everybody!
I have a Bassboy that is only controllable via midi CC.
That is not so very fun so i want to get some pots and switches to increase the tweakability.
The brains behind the bassboy has constructed a controller named Ten-O-pots but its not yet for sale.
Could you guys suggest any product that could do the stuff the Ten-O-pots do?
Of coarse i want it to send all the inspired tweaking CC stuff to my DAW.
What to do?

Looking for a polivoks PCB/kit/assembled board

dubtoms — Tue, 15 May 2012 20:18:41 +0200

Hi guys,

As I'm currently building a Shruthi XT wasp edition I will need to include a polivoks filter in it at some point

Since no PCB are sold separately from the digital board and I don't know when i'll embark on a second kit I would be interested if someone had a spare PCB or, even better, a ready to use Filterboard to trade.

This is just lazy me trying to avoid the hassle of etching a PCB myself but hey, who knows, maybe one of you can help...

[fixed] issue adjusting screen contrast

dubtoms — Thu, 17 May 2012 11:12:34 +0200

Hi guys, I'm on the verge of completing the assembly but I have issues with the lcd (yeah I know same old problem...)

I've been twisting the trimmer for turns and turns (for more than the 24 indicated without clicks) but I saw little improvement : at first I just had a blue screen... then white squares came in, now I can painfully distinguish parameters adjustements as I turn knobs...

Any clues ?

Problems with standard case .svg

Soldering vs. music making

rumpelfilter — Tue, 15 May 2012 15:54:54 +0200

This is kind of an open mic question to all of you here on the forums:

Do you consider yourself more musicians or instrument builders or electronic engineers?
Do you spend more time soldering, making and hacking or playing and composing music?

AVRISP and tutorial midi

Nedavine — Wed, 16 May 2012 12:54:32 +0200

Hey, I think I've finished but I have a spare 6 pronged thing that fits in the 6 AVRSIP holes. Have I missed this somewhere?

Also on a side note. I followed the tutorial to the letter and in doing so I attached the LCD before attaching the midi inputs. It might be a bit obvious but I completely missed it. Maybe a note would help fellow bad builders like me?

Looking for resources on Learning Hardware Programming

n8bit — Wed, 16 May 2012 17:52:40 +0200

Hi Guys,
I have lurked around on this forum for years, am building my 3rd and 4th Shruthi, amongst a whole load of other DIY music stuff however, I have reached the point in my skills and building that it is becoming imperative to learn to program. I don’t want to learn C or C++ from a book that is going to stick me in a windows machine and learn impractical exercises, I want to learn on hardware, like Atmega, or PIC. Essentially, I want to be able to program my own nifty gadgets most likely much simpler than the Shruthi and WTPA, but still adequate. Is there/are there any REALLY good resources to self teach programming? I have programmed a little bit, but I was younger, and it didn’t seem to make sense. I am a much better learner now and can generally pick things up pretty fast. Any tips?

4 Pole Mission Distortion

Thealphajuno — Mon, 07 May 2012 21:37:50 +0200

Hello, I have some troubles with my Shruthi 4-pole M
In LP1 and LP2 modes, the sound level is very high and very distorded. It sounds like it's passed thru a Guv'nor distortion pedal..
Pichenettes took a look at my filter board and it seems looks ok.
I need some help to fix it please...
I am not an electronics and my skills are very limited .. However, I have an oscilloscope to make measurements if needed.

gorf, midibox gm 5X5X5 semi builded.

flo — Fri, 11 May 2012 19:40:04 +0200

hi!
i have here semi builded pcb of gorf and midibox gm5x5x5 that i will not finish.
( i lack some part, and don't have the time to source them, and finally not the need for them. bought them when i was jobless for occupation, but now my free time is rare, ...)

I think the job done on them is good, but can't certify it. So if they interest you, and your name is familiar to me and to this forum, (i read this forum for a long time now) this is what i think: i send the unit to you, you payed just the postage, once it's completed and functionnal, you payed me the money. You have to be quick on it.....

i Will definitely be interested by sids chips....

open to offers...

unused C64, what can I do with it?

rumpelfilter — Sat, 05 May 2012 19:20:44 +0200

I have a very nice Commodore 64 C, I put into a brown breadbin case with heatsinked ICs and a nice greenish monitor from philips from back in the days. I used to play around with it with the MSSIAH cart, but since I have built myself a SammichSID I don’t use it anymore (btw. If anybody is interested in a MSSIAH cart, I’d be willing to sell it). So I was wondering. Since I love my C64… what could I do with it? Play games? Maybe buy one of those 1541 Ultimate carts, or what else could I do with it? I really don’t want to sell it, but it’s just catching dust right now…

resources for an aspiring synth nerd?

aberant — Tue, 15 May 2012 21:21:19 +0200

hello all! so i think this forum is full of the types of people i've been trying to find... how does one go about learning and designing synth parts. is there some book that's the bible of such things.. or do i need to go through schematics for modular parts i find online.. or? i've even been going over patents released by bob moog to try to find ideas..

i know enough EE to not blow up anything, and am pretty confident about my programming skills.. i just don't exactly know where to get started
