Yes! I do have some extras - just drop a PM or email me...

Pp'd for mine, can't wait, this looks super cool!

Will these work fine:

In place of (in the bom):

The only difference I notice is 100 PPM/C on the latter vs. 50 PPM/C on the former.

Should be fine!

payment sent for another PCB/chip.
looking forward to building a 2nd one.
and thanks for the folder loading in the software greg!
makes things so much easier / faster now.

loving the folder loading in the new software, its working pretty well.

greg, any chance you could implement a clear all banks button feature?
sometimes i want to load in a bunch of waves to audition them but then clear them all out to load in a new bank.

thanks!

surgesg · Posted: Wed Apr 11, 2012 12:34 pm Post subject:

well, if you're just going to load a new bank, you could just overwrite what's already there, no?

asterisk · Posted: Wed Apr 11, 2012 12:50 pm Post subject:

oh yeah, duh, didnt think of that. ill just load a new folder and it will write over the previous banks right?

ive found that sometimes the first sample doesnt load up but the other banks do, anyone else having that problem?

Yeah, i noticed when i was trying to put saw on first sample to use with z3000 tuner and it never happened.

I have also notice that the modulation of the waveselect and blend doesn't happen if the pots are all the way down(not talking about attenuators here) Anyone else noticed that?

I'm interested in grabbing one of these!

One question though: would it be difficult to modify the code to display the wave number to either a 2-digit 7-segment display or to a set of LEDs similar to the Mini Wave? I've done some microcontroller programming before, so I'm not worried about my ability to do the programming, but rather if the pins are available from the ATmega328.

Also, is it possible to operate this module with +/-15V? What component changes would be needed?

Depends on the number of pins needed to interface with the display. Most of the ATmega328's digital outs are free, however.

Cable · Posted: Sun Apr 15, 2012 2:04 pm Post subject:

As long as there is 6 pins you should be able to show 64 different numbers at least with binary..that could be nice..
It is 64 waves per SD this does right?

surgesg · Posted: Sun Apr 15, 2012 2:05 pm Post subject:

Right - that works out nicely.

raisinbag · Posted: Sun Apr 15, 2012 2:31 pm Post subject:

Wow that sounds super cool. If you are able to implement that ability please please please let us know how to do it.

Is the tabula rasa able to run down to LFO frequencies?

Can't wait to get mine going....

For anyone else in Australia, I think I've found a supplier for the SD sockets:

http://littlebirdelectronics.com/products/sdmmc-socket-for-secure-digi tal-disk-or-multi-media-cards

They are a sparkfun distributor, so I think they are the right ones.

Boards/chips just arrived!

We are currently having our car repaired, so I will be shipping out toward the end of the week.

CJ Miller · Posted: Wed Apr 18, 2012 5:51 am Post subject:

I am considering making some of these for my 4U project, but I am unsure of the output. Does the AC output work as a modulation source for other modules? Since there is a spare opamp, couldn't I use it to buffer the output?

Nearly done mine now, can i ask what other people have done with regard to grounding the jacks / extra attenuators?

I thought there was some posts in this thread regarding that but I cannot seem to find them now =/

The grounding pics were in the original panel thread:
