OK guys, this is getting fun...

The record gate input is working. The only problem is that the speech chip seems to require about 100 milliseconds (.1 sec) to go from record to play mode. I can't find anything documented about that, but anything shorter locks up the chip. It's NOT that way going from play to record mode however, which is a good thing.

This means that if the gate input remains high after it goes out of record mode, there will be 100ms of silence before playback starts. I'll continue to try different fixes, but as of now, that's the story.

Also note that any playback must end before recording (or playback for that matter) can begin, but I think I've pointed that out before.

Minor mod to the front panel.

In place of the push button for the gates, I'm putting a 3 position toggle. UP holds the gate input high (continuous looping), CENTER allows the Ext Gate Input to control, and spring loaded Momentary DOWN will be the same as the button. Capiche?

Anyone have additional input? Bring it on - It's hard to create in a vacuum. very frustrating

Maybe if you posted some demos. Maybe there are some but I didn't find them in what I thought were likely places. I'm curious about sound quality and latency. A simple demo of it embedded in a rhythmic patch would be helpful.
dslocum
Hmmm. Demos. I just realized I haven't really got a great setup for making demos, but I put these two together this morning. They are simply awful creatively (I'm a shoe-maker remember :-) ), but it should get a bit of how the SampleCorder sounds in the context of a slightly bandpass filtered rectangle wave sequence. (Note to self - Need more sequency toys)

Both tracks use a dumb 16 step sequence, with a "duck" sound at step 9. "Duck_Baby" are just samples found on the web and triggred at 9 & Done outputs of my sequencer respectively. "Duck_Shot" is the same duck at 9, but a nice sharp percussive snare shot at Done to show that the unit really fires quickly with no percepable latency.
dslocum
This is turning into more of a a blog, but hope it helps.

Now that I've had some time working with the sequencer stuff, I've discovered that the gate functions are not all that useful, so I've decided that the previous gate inputs should really be trigger (one-shot) inputs.

So now, the module is looking for triggers (one-shots) on the inputs, and ignoring continuous gates. I'll rename the inputs to "Trig" or "Trigger"

Before:
You could hold a gate input high and it would repeat as long as the gate was high.
After:
It plays once per gate (Trigger)

Before:
Gate inputs would cause looping if held high.
After: Any looping will need to be done with external patching.

Does that make sense????

I'll post more as time permits.

I think triggers is easier to use than the previous gate/repeat idea.

Would it be possible to have a separate Done pulse output for each of the two samples?

If one or more pulses arrive after playback has started, will they be ignored (better I think) or will the sample play again as soon as it gets to the end? The benefit of not having "pending" triggers is that each time it plays it's doing it on cue.
dude
would it be possible to compare what similarities and differences this device shares with the modcan cv recorder? despite all info in this thread i am still having a lot of trouble understanding what this thing will be able to do. or maybe it is still under development to the point that a comprehensive feature set or list of possible uses is out of the question?

Excellent observations, and pretty much the same conclusion I came to after my recent "trial by demo fire". Sometimes things sound "engineering" good until you really need to make some practical demos - then - "OMG, what was I thinking" very frustrating

I'll be adding a Done output for each Bank per your suggestion, the two Gate inputs will now ignore any inputs while playing, and a couple other minor implications will be rearranged. I love the flexibility of CPU based logic for this reason.

Thanks for the input.

Dude,

You put me one the spot, but no problem applause and here's my stuff...

Yeah, I'm kind of trolling for ideas and feedback. BananaPlug just gave me a couple cool suggestions, and I'll be changing-up my thinking on this module shortly.

RE: Comparing the Modcan CV Recorder to our SampleCorder....
While it's a bit premature to do so, I think I can honestly state that these two products are simply not competative. Meaning that I can't possibly compete with Modcan's superb DSP based, multi channel design based on 4 channel cost and performance. While I don't own one, that Modcan unit is an EXCELLENT value! If you need 4 channel audio AND CV recording, please consider buying one. Shoot, I'd buy one if it was MU and not white!!

BUT... If you're in need of an MU audio only analog solution with 2 record/play banks at a fraction of the price, then maybe the SSL unit might be right for you.

Please stay tuned....... This is fun!
dude
cool, staying tuned. the main diff is the basis of being used for audio where bruces is geared toward cv. perfect way to keep it simple for simple folk such as myself. thanks!
dslocum
...That is the question.

Based on the input you've all given (thanks!), once a Bank is triggered, the new firmware can go one of two directions.

1) If a trigger (gate) input remains HIGH, it will loop when done.
2) If a trigger (gate) input remains HIGH, it will NOT loop (retrigger) when done.

In the case of 1), it's more like a gate which some of you said is not useful (I agree). In the case of 2), it's really a trigger / one-shot (which I tend to think makes more sense musically.

Thoughts please.

EDIT: After looking back at this thread, I think I already answered my own question. Triggers! But thoughts still welcome.

Actually, yes. I have an announcement!!!

Jean-Jacques Perrey has officially endorsed the SampleCorder - Signature on the module and all !!! applause Rockin' Banana! nanners It's peanut butter jelly time!

I'm still finalizing a couple things before going into production so it's still a few weeks away.

Stay tuned.....

So . . . a lot has been announced and produced while this module has been lingering on the back burner. Is it still going to see the light of day? Particularly with the addition of the pitch cv in, I'm still eagerly awaiting it.

I kind of imagine this being a module that would delight my nephews the next time I force them to play with my synth. (I know you must be hoping that people use your modules to compose masterpieces, but amusing elementary age kids is the best I can do!)

Cheers,
Brian

I was kind of wondering who would be first to scold me for taking too long for some things. d'oh! meh

The SampleCorder is alive and well, waiting for some switches that should have been here a month ago (tomorrow, I hope), and some final firmware tweeks. Once I'm comfortable with those, I'll be ordering the PCB run. The panels are already in from the vendor and they look GREAT with JJ's signature.

Take heart, it's coming. Thanks for the patience folks. Not much long now I hope. I've got a lot of time invested in this, so selling one or two would be most welcome. very frustrating oops

Any news on this little feller? I've built a simple sample/player/recorder/ looper for my system, but this one looks like it'd be much nicer...
dslocum
Just to avoid any misunderstandings on what this little fellow REALLY is all about...

1) It is NOT a looper
2) It is NOT Hi-Fi, but it IS way better than 8 bit
3) It IS a pain in the ass to record a sample "properly"
4) There is NO wave editing capability
5) The sample MUST play to the end
6) Two saplmes can NOT play at the same time
7) It is lots of fun

Frankly, I would have given up on this project LONG AGO if I didn't have soooo much bloody time and energy spent on making this stupid speech recorder chip do something that it was never intended to do. Yet I have received wonderful encouragement from Dana Countryman & Jean-Jacques to complete it. And so you have it - or will shortly.

My production crew (read "wife-slave") has been working on the PCB stuffing and I hope to make the first few available in about 2 weeks time. Recently, our regular day gigs have seriously hampered both of our available time to create modular madness. Please PLEASE, forgive us.

I've decided that there will only be 25 JJP SampleCorder units produced. PERIOD.

My "sample" unit (SAMPLE), one each for Jean-Jacques (SN 0001) and Dana (SN 0002), and the rest for you folks, leaving only 22 to go around. It will be priced a bit higher than some of our other modules because...

1) There's lots of wiring to the front panel involved (couldn't help that)
2) It's a LIMITED EDITION
3) It's a COLLECTOR'S ITEM (yeah right)
4) It has Jean-Jacques endorsement. (YEAH!)
5) I doubt I'll even sell out of these 25 units. My loss, your gain.

Seriously though, I hope you guys LOVE the JJP SampleCorder !!!!

Cheers,

Doug
bwhittington
Oh, so these are coming up fairly quickly! I want one. Have you finalized on the price? Any preorder stuff?

Maybe you shouldn't be so down on its prospects. I think it sounds fun.

Eagerly awaiting for mine to arrive. This will be on my live show rig setup for sure I can only imagine the mangling I can do live zapping some insane samples from my ESX into it and destroying it with my modular setup. Oh the possibilities...
dslocum
Hey guys.

It turns out we have one last JJP SampleCorder available. It's been sitting on my bench awaiting minor troubleshooting, but got put aside because I wanted to concentrate on getting DDVCO's out the door.

PM me. First $265.00 + S&H gets it!
fac
Wow. *THE* last one? As in there won't be any more? How many did you make?
dslocum
Sorry Folks. It has been spoken for.

No "current" plans for another run. Sorry.
Putte
No more Samplecorder, ever? And I just got the money for it!
