at least with the MIDIbox CV, there's provision for setting the pulse width:

Code:

The pulsewidth of the clock output can be configured in pieces of 500 uS. By default it's 1 mS:

; 0 -> 500 uS
; 1 -> 1   mS
; 2 -> 1.5 mS
; etc...
#define DEFAULT_EXT_CLK_PULSEWIDTH 1


A pot (or even a CV!) could be hooked up to one of the PIC's analog inputs to control this pulse width variable.

Thanks Sneakthief. I wasn't aware that there are problems with the Blacet PIC. Good to know, though.

I can endorse the MIDIbox kit too - the sync works well, and it's a tiny board.

The MIDIbox monitor is a cool project in its own right, a good first MIDIbox, and a very useful tool. Cheap too - the core, a 4x20 LCD and a couple of buttons.

would this require high programming skills?

fonik - no, i think it's relatively easy. i'm consulting some gurus right now and will have a solution shortly. it's just a matter of assigning one of the analog inputs to pulse length variable.

if you like, i can compile it and send you the .hex file to upload when it's ready.

Hi, I was wondering where I could find the schematics for theese projects? are they public? some links seem to be dead that point to them?

If you're talking about the MIDIbox project, then look no further than http://midibox.org

PostPosted: Sun Sep 02, 2007 12:02 pm    Post subject: VC Clock for Klee or Other Sequencer Reply with quote  Mark this post and the followings unread

All,

I just finished building a voltage controlled clock for the Klee. The design is based on the Roland M-182 sequencer and it works great!
Features:
1.) Voltage Controlled
2.) Freq: 0.14 Hz to 33 Hz, (7s - 3ms).
3.) Clock and Gate outputs with variable Gate width.
4.) Start/Stop button and ext. Start/Stop
5.) Temperature stabilized.
6.) Free run and single-step.

I have enclosed the edited schematic and the original can be found here:
http://fa.utfs.org/diy/roland100m/index.html

Fairly easy to build.

Regards,

Tim

Hmmm....a very nice addition indeed!

And the Klee schematics - AAAARRGGGHHHH! I was going to fix the swapped pins on the TL074 sections, then re-upload it, but it's not going to happen in a while (maximum effort going into Klee proto). So, thought I'd upload warty version 3.03, which is quite usable, but it's not on this computer.

Anybody got the 3.03 zip file handy?

Well, look at his avatar - wouldn't a crown of laurels look good on there?

Anyway, here's a sort of plea for the Klee thread readers: I'm uploading a draft of part of the Klee ops manual. It's the section that attempts to describe what it is the Klee does. This thread is huge, and the information is so scattered throughout, I wonder if what a Klee Sequencer is generally known by more than a few people.

So, this portion covers the basic fundamentals of the Klee pattern generator and gate bus - it stops right at the description of the merge switches (I'm still working on that). There will be a separate operations section (programming the pattern, clocking it) - this section is more along the lines of understanding the underlying nature of the beast.

I certainly would appreciate feedback - is the style too simplistic, unnecessarily technical, confusing? Does it help to clear confusion or serve to inflict it? Please let me know!

Cheers,
Scott

Edit: It probably would have helped to number the pages - I can fix that and upload a numbered version (and fix a couple of minor grammatical errors, and one error right after Figure 22 - it should read "step three selects stages three and seven" not "three and four").

Edit 2: Numbered version uploaded, fixed the figure 22 thing.


hej Scott. Could you reupload missing "know_the_Klee_draft2.pdf" file? thanx

[Edit by Blue Hell : please follow http://radio.electro-music.com/forum/topic-24821.html for the docs]

Actually there was a later draft of "Know the Klee" (rev 3) posted here:


http://electro-music.com/forum/download.php?id=8646

Things are getting pretty scattershot for the Klee Sequencer - I'm going to try to consolidate the info for the electro-music Klee Sequencer PCB project to this thread (which was formerly the original PCB poll, but is now more of a build thread):

http://electro-music.com/forum/topic-19278.html

This thread, which was about the development of the Model 2 Klee, which is essentially the electro-music thread, is going to be unstickied to make room for a new, more useful thread for everybody.

As things progress here, things tend to get lost in the roar of what's going on - I plan to sticky a new directory of projects so that everyone's PCB project can be found easily through all of the threads. I figure this will be handy for those of us that have been here a while, and for new members who may still be coming to grips with what's offered.

Cheers,
Scott

All,

At Scott's request I have edited the pin numbers of the TL074 op amps in the Klee 2 schematics and I am re-posting them as version 3.02A.

Regards,

Tim

Scott Stites wrote:

One other unrelated note: the gate bus schematic defaults to +5V gates and triggers. That is determined by running the outputs of the LM324s through 3K with 1.5K to ground. This divides the original 15V level to 5V and creates a 1K output impedance, because the 3K and 1.5K are essentially in parallel.

One thing has bugged me about that - not all synths will respond to +5V. Though it's the Electronotes standard, it's not a universal standard. For example, Ray Wilson's EG's will not respond to those levels. This is easily remedied - instead of running the output through 3K with 1.5K to ground, run the output through 1.5K with 3K to ground - IE, swap the two resistors around. The same output impedance is maintained, but now the gates and triggers will be 10V. That's a personal preference decision that can be made at time of build, and I'll note it on the updated schematics, which are coming down the pike.


Only curious,

Is there any inconvenience, any incompatibility, running the gate trigger outputs at 10V?

Well, not with my system. I know the electronotes standard uses 5V gates and triggers, so that's why I put the option in. I seriously don't know if those types of levels would bother anything, or blow anything up, if it was designed for 5V levels. Maybe someone could kick in with more info on that.

BTW, Ray's EGs now do respond to the lower levels. I think I built my MFOS EGs (on proto-board) about 2.5 seconds before he designed some that respond to lower levels.


Cheerios,
Scott

@sound:
how great you digged the origin klee thread. IMHO it is one of the greatest e-m threads ever! it is such a great example of sharing, collaboration and such from the beginning - outstanding and striking!
