Oh, in case anyone wants to see an attempt at a flash cart for the Lynx:

Cost $$$ and can only store one EPROM image (and maybe only one tune! We'll have to see)

OK.  Here are my latest progressions!  I'm not that happy with the track but it's 4:35am and I've got work tomorrow.

http://lynx.syntaxparty.org/tests/cTrix-Lynx-TEST2.mp3
(Made this going back and forth to MODPlug but also in the actual tracker)

A few things I noticed / suggestions for the software:

- Auto add .sin automatically when saving instruments from simple instrument
- Sometimes crashes if I try to tune / tweak instruments while playing back from tracker
- One of the notes in the tracker shows up as an H?!
- Still gets stuck at sequence pattern 10 and doesn't keep playing (you'll see what I mean)
- When I use the play in the simple instrument window; it's at a different volume than when the tune plays back - more so, the envolope is different.  I know why this happens, it would just be handy to have a "master velocity" control in the simple instrument window maybe? (easiest fix!)

Requests / Ideas

- when adding notes in tracker have option to play the rest of the line along side note being added in
- have an option when using arrows up and down to also play that line (could be same as above)
- A one click exporter to generate WAV samples of all the sounds as a sample pack (takes me about 20 mins to sample and chop up otherwise)
- Recognise the volume command "Cxx" on MOD import & implement note volume.
- MOD import optimzer / pattern optimiser to remove repeat patterns.  (not vital, I can do this manualy still!)

Sounding good though!  Chipper is certainly in a usable state.  I'm just learning how to make it tick at the moment :-)

The source files are at: http://lynx.syntaxparty.org/tests/ctrix … source.zip
The track runs at 1000 (4us*250)

Ps. How to compile this to something I can drop onto a cart?! ;-) (I have that MOD converter half working)

Just top part "-)

Sample and listen is best policy on rates.  You usually find a sample rate which trades fidelity for file-size. Although don't go on Nyquest as something like a kick or sine bass will ring annoyingly at say 8khz... and will sound a lot more rounded at say 26 - 28khz.  Because of the way an Amiga aliases the sound, sometimes hats and the like sound crunchy and awesome at lower sample rates. Don't rely on your PC to correctly preview what a low sample rate will sound like :-P  (it fills in the "missing" samples on an upconversion to 44.1khz/48khz with a curved waveform instead.  The amiga will leave the sample values as DC with square amplitude changes unless you have the filter turned on)

Sometimes a sample rate is chosen so that the "highest" note for that instrument hits the top A# (highest non-tempormental safe note). I try to do this for leads and rounded bass instruments. I've lost count of the amount of times I've gone out of range by a note or two and had to go back and knock a few Hz off the samplerate then transpose an instrument a few notes down.  Else you end up octave-resampling for the sake of one or two notes!

Also, I posted on this a few days ago, though it seems no one picked up on the topic.

Sorry 'bout that mate!  I did look though the list before posting but glanced over it (was looking for "Rockit" rather than "kickstarter")

Hopefully between the two of us we can raise some awareness.  It's the open source + commented code + MIDI support which makes it look impressive to me.  I really hope this takes off; but at the same time, if he gets to many orders, it could go the way of so many small operations... (talking of which, my BC16 still hasn't arrived after 3 years)

Forgot to grab mine at Soundbytes... did ya keep one for me?

I'm surprised no one has picked up on this one yet.  This lil fella is called the "Rockit 8 Bit Synth".  I just ordered one.

Matt (builder) says: "The synth makes deep fat bass, chip noise leads, sci-fi robot weirdness and eveything in between."

Specs:

- Fully Open Source Hardware and Well-Commented C code
- Digital / Analog Hybrid Circuitry
- 2 Digital Oscillators with 16 waveshapes
- 2 Low Frequency Modulation Oscillators with 10 destinations
- Analog Filter with Low-Pass, Band-Pass, and High-Pass with Envelope Control and External Audio Input
- Analog Voltage-Controlled Amplifier with full Envelope Control
- Drone/Loop Mode for Playing by Itself
- 19 Knobs to Twiddle / 8 Switches / Sound patch save & recall
- Full MIDI Input and Output

Currently $125 in kit (+ postage & while kickstarter lasts).  Doesn't come in a case - but he's looking at options.  You can also get a prebuilt unit.

http://www.kickstarter.com/projects/790 … -synth-kit

Obviously it's unproven at this time and there are only the youtube demos to go by - but it seems like a module with a lot of character and the fact it is designed for "hackers and electronics enthusiasts" and "will be an engaging platform for synth programming and exploration" ticks a few boxes for me.

I'm wandering (if it doesn't come with a case) what the best options for mounting it will be?  I'm thinking mounting it flush to a Tupperware container lid and maybe extend the I/O so they are not directly connected to the board?  Replacing the pots / switches, etc, just seems a little tricky - although might need doing if the onboard ones wear out.  At any rate - looks like fun and worth it for the pass filters alone :-)

So I just played with a Monotribe - one of the first review units to arrive in au from jp.  Really fun gizmo but IMO beyond the initial warm / fuzzy feeling is an instrument with at least 3 knobs missing.  The $70 monotron is so simple you have no expectations but for $290...? (price we pay; and our dollar worth more than US? wtf?!). 

My main gripes are: Drums (no way to shape the sounds?! what?!), No MIDI (forgivable), OSC (no sine waveform? no sub osc?!), No ADSR.  Surely Korg could have added a few more controls and made it at least semi-on-par with "the big boys" for the sake of a few bucks.  If this were 2 osc with a detune + sub with a filter ADSR, and had also had a way of shaping up a phat explosive kick - then it would have been in everyones studio worldwide and we'd all be making Acid techno and detuned hard house again.  They'd be so good the government would ban them.

That said, it's a fun analogue "toy" and I'm hoping that peeps will start modding them and unloack the additional features and controls.  Apparently the PCB is marked up quite well but I wasn't allowed to take the case apart and and look!!  So here's hoping...

you can't choose a custom samplerate?  It's also SIGNED that you want ;-)

I love you guys, but Im so glad thats over. What a week. At least everyone had fun

It was rad Kristy.  Huge UPs to ya :-)  I think everyone has left town now?  Ended for me with a chill hack session with Vicious last night until 5am (ST / Lynx)  It was the weekend which just kept going and going!

I got audience recordings of the night BTW.  Chris; happy to marry them up to a desk recording if you got it? (or send you the live sound) :-)

Then there is this  ;-)

The standard rate for the Amiga (to be in C) is 16726Hz or half that if you want to be an octave lower.  Throw all the modern day "standard" 44.1khz and 22.05khz convention out of the window because there were no standards back in the 80's!!  You'll want to export using a program that can write raw signed files - like early version of Audition (or Cool Edit) and I think Goldwave still supports signed / unsigned conversion too.

As Akira says tho, the easiest way to get your samples across is to use MODPlug or Flakeytracker and "save as compatible".  The take the samples across in a MOD.  Again - 16726hz is the tuning point for C ... and you can do up to about 29000hz if you want clear / clean audio for high hats or something else critical but beyond about 29k it'll be out of range.  I'd let Milky or MODPlug do their own 16bit>8bit conversions rather than saving 8 bit out of your DAW as they will both do a rough quantize which usually sounds better than a "dithered" nuskool conversion.

(ps. Max sample length is 32k - which will be 64k as a 16bit file)

Would this work with Richards VicMulti flash cart?

- Easy to share
- Easy to back up

I'd venture to say that no music documents are difficult to back up or share, given how big hard drives are and how easy it is to share even hundreds of MB of data today. As for sharing in particular, I think, rather, that anything that requires the other end to install new software, will be a nuisance. I.e., it's easy to share for what you and your friends are already using.

\

MODs are piss easy to share.  As are ITs or XMs or any tracked files.  Usually less then a meg.  The reason I don't use all this VSTi and DSP crap outside my day job is because if I send a project to someone, their system has to mirror mine.  Plus to have the whole project - with samples - is a huge collection of files that need to be in the right folders and it's hard to version track and merge.  It's just messy.   

Tracking software is simple to install. Infact IT DOESN'T NEED INSTALLING most of the time!  You just click on the EXE and it runs - hey, why not send the EXE in the file with the project?  It's all freeware anyway and still under a few meg.  Plus the formats are opensource, low-CPU usage and easy to implement into games / demos / whatever - so there are a huge amount of reasons to still be using tracked formats.  Especially when you can pattern jump and have the logic mute parts, etc, to match action of whats on screen (say, if it were a game).  I personally think there are a sizable amount of commercial and creative reasons to still use the tracked formats.

Most of all - everything is in the same window (most of the time).  None of this painfull swapping between tabs and clicking in and out of modes, etc - although that's just a pet hate of mine.  For me, all notes & controllers - BAM - in front of me is the way it feels the most natural.  (end of rant!)

the Gameboy is something you (can) hold in your hands. It's something that gives the impression of being tactile. It's easy to imagine a close analogy to a "real" instrument. You just can't do that with a laptop or even an AMIGAAAAAAH!

You can turn any console into a ridiculous holdable format.  You just have to be creative ;-)

Yes, I do plan on doing a public release of this in the next month or so with a tutorial.  Just lettin' it in the wild with a few testers first.  Anyone else who wants it before this time will just have to find someone with a cTrix usb stick ;-)
