A hard time? They nearly all do aside from newer ones. Grab something used at a thrift shop. If you're just starting out, you don't need something new and huge. 
If anything, pick up one of these:
http://www.newegg.com/Product/Product.a … 10213400:s
17 bucks. Can't go wrong. 
Yea that IS a good price, I picked one up at a thrift store for $25 and am very happy with it! Very good feel and nice size to enter notes into the PC. I suck playing a KB so it's fine for my lame one handed 'style' If you can really play, you would prob want a larger KB.
As to the Shifmore how-to, it's kind of a 'why?' thing for me. If you have the interface, why not just use DIN sockets on the Arduino? The Arduino needs to be setup to send and receive Midi anyway and cutting up the interface just makes it less flexible. I suppose if you really don't have the space, hardwiring the interface into the same case is good.
If you really need USB Midi/Arduino I would port to a Teensy that supports USB Midi directly. Didn't Littlescale do a Teensy Arduinoboy?

So here is a link to my preview .NES. There is a copy of the User Configure file that lists the included NSF titles from the Fami Mini Compo 10. Runs in Nestopia for me, can't say with other EMUs. The Pad 1 controls:
Up/Down - Select song (all are 1 song NSFs)
Left/Right - cycle thru the 7 NSFs
Start Button - Play/Stop
This build doesn't have sync active so the NSF plays at the 60Hz (normal) speed.
NSF 1,3 and 4 only play for a short time and then force a bankswitch, Still investigating the cause but I don't know the source of the NSF play code.

Hey guys, kind of got side tracked a bit, needed more research into Midi Beat Clock but I think I've figured things out (?).
Along these lines; been working on an expanded ver of VegaPlay (SNROM mapper) with multi NSF loading and FamiSlayer type sync. It handles 7 NSF, just under 32K each (you lose about 16 bytes @ $FFF0 for the vector table and reset bankswitch trampoline). These can be multi song NSFs as per the original VegaPlay.There are compiler switches to allow you to build: A. for standard play back or B. for sync playback, as well as packing the output as a .NES (for EMU) or a .PRG (for simplified flashing to a eprom) .
Added a User configure file to simplify setup before compile. Just need to fill in the NFS titles and the NSF Load addresses. No more stripping of the header from the NSF, just have the NSF in the build folder. I'll setup a dropbox for a test ROM.
ATM it handles NSFs produced in FamiTracker but bombs with NSF play routines used in Goat Tracker (I think) and others. Some of the NSFs I tested (from Mini compo 10) that had a load address at $8080 always crash, others force a bankswitch to the next NSF (bomb). I tried a few things as noted by NoCarrier; but seeing as I prefer FamiTracker it's not too big an issue for ME.
Still some testing and code cleanup/docs before release, but soon!
Hardware wise: Just finished wiring a NES Midi Beat Clock to Sync24 board, but it's based on a 16F628 and code based on http://obsoletetechnology.wordpress.com … converter/ along with my own additions. Still need to test before I post much more info. Kind of plan to add Midi Clock/Sync support to the Teensy code, cause this is the most useful application for me ATM.
Also got a few other things on the work bench; it's not easy being ADD

Sounds like you worked out a fix, but if you want a simple mod
http://atari4ever.free.fr/ find "AUDIO.ZIP" at bottom of page. Pulls the audio from the Hi-Rez connector.
There are also mods to tap the 3 channels from the AY chip, but are more involved.
Good Luck.
Yogi
EDIT- just saw your last post, same mod
Payday wrote:So for flashing famislayer with nsf do you have to re upload the rom to add a new song every time? .
Yes, FamiSlayer and Vegaplay are wrappers for a NSF; they produce a ROM that is runnable on hardware or an EMU. The NSF is just the the music data and player code, and must be called at a regular frame rate, usually at the video rate. The PowerPak has NSF player code just like most EMUs so you wouldn't need VegaPlay to build a ROM. For making your own cart, you must provide the code to setup the system and continually call the NSF play routine, this is what VegaPlay does for us. FamiSlayer waits for a 'button press' before playing the next frame of the NSF.
You can make a multi song NSF in FamiTracker and if it's not larger then 30K, use FamiSlayer or VegaPlay to build a ROM. But each time you will have to re-flash your cart with your new ROM.
Yogi
Most people use PowerPak or N8 to play NSF direct, but there are other ways. Famitracker exports NES files that can be used or you could use VegaPlay of FamiSlayer to pack a NSF in a ROM file that can be played on standard NROM cart.
Check out this wiki-
http://wiki.nesdev.com/w/index.php/NROM
You could replace the chips on an NROM cart; but for this you need to remove the chips on the cart, flash new chips with a burner tool and resolder the new ones on the cart.
A lower cost route could be one of Infiniteneslives' flash carts. With one of these you would need a cart edge programmer, the original design is called a Kazzo and INL has an updated design. His site-
http://www.infiniteneslives.com/products.php
There are a lot of mapper options but VegaPlay or FamiSlayer only uses NROM (which is no bankswitching). INL has a NROM board that should be released very soon.

Interesting, Cortex ARM based ? Liking the thumb drive.
EDIT- the above link didn't show much, but this has some info

Oh man this looks cool, really liking the 'HDD-to-USB-to-EMU Floppy'. Hoping this makes it to the Atari
irrlichtproject wrote:Ah, I didn't know that. Never bothered to back up any ST floppies tbh. I only do it the other way around, and hope the disks don't die on me during a show 
Anyway, thanks for the info, yogi.
If you want to dig deeper into things I'd certainly recommend an SD card based solution as well, but just for having a quick play with the machine it seems a bit too pricey.
Cool.
Well the OP only has a Macbook so if he wants to do anything with the ST disks, will have to commit to 'some' HW. Could think about a old A$$ PC (can find em on the side of the road) just to use the floppy interface. Keep it in a closet most the time, till you needed to transfer files. With Win98 SE and a USB thumb drive you're all set. Would definitely be very cheap if you have the space.
Yogi
Sorry I miss this when you first posted, Very tasty tracks! After the game's done you need to get an album out, really lik'en the styles!!
Yogi
In order to read and write ST disks on a PC/Mac, you need access to the floppy drive's controller; to setup the correct low level and high level format. A USB floppy drive doesn't allow this.
http://info-coach.fr/atari/software/FD- … dd_formats
The best solution, IMO, is to go with a HxC SD or something similar. If you are archiving some old disks it will be a bit of a pain transferring on the ST from the floppies to the SD; but you will only need to do it once. In the long run SD cards are way more reliable and moving data between the ST and PC/Mac is way easier. Just my $0.02
Yogi
Hi, welcome to the Atari!
For dealing with floppies, take a look here
http://atari.8bitchip.info/floimgd.php
But it wouldn't help with the USB floppy drive. The floppy on the PC/Mac side need to be controlled at a low level that the USB interface doesn't do.
So the options are: install a floppy on a machine OR get a SD floppy emu for the ST; like this
http://www.lotharek.pl/category.php?kid=7
Then you can transfer stuff with SD cards.
For trackers, well there are a lot of choices.
maxYMiser is a good start http://www.preromanbritain.com/maxymiser/
Yerzmyey has a break down on what he uses http://ym-digital.i-demo.pl/soft.html
But there are lots more, so look around. You'll find some great stuff out there

Major props to Aly James! Your softs are excellent and I for one very much appreciate your efforts. I totally understand where the frustration comes from (same boat here) but it should not have been directed towards you.
That said, nice tease Can't wait for the debut (been thinking about something similar; just got a YM2612). Knowing that you'r involved in supporting the HW is very good news!

Timbob wrote:Are there many different nes coloured carts then? I thought they only came in grey and gold for zelda...
Yes, the original Nintendo NES shells didn't come in any other colors. Some other game producers had black, Tengen I know had some black shells (but the PCB mounting is very different then the standard).
Bunny Boy's shells are aftermarket repos from his own moldes. He may help you out, I would think he has some stock for the repo and homebrews they still sell (?)
infiniteneslives over @ Nesdev.com has plans to do a run of shells in the near furture, spring/summer. You could keep an eye on his store http://www.infiniteneslives.com/index.php
or check on the nesdev boards for updates.

thursdaycustoms wrote:The components for variable clock kits are insanely expensive!
But aren't the components themselves very cheap? I would say such price is for labour and design rather than for the material, no?
Yea, about half is parts/PCB and for these SOT parts pre assembled it is worth it, for most. When you factor in the cost of ordering single quantities with S&H and making a PCB (either DIY or sending out to FAB) you'r very close to the cost of the assembled unit.
Going the DIY route can be fulfilling, but not always cost saving. Having a well stocked parts collection helps, but I've got more then a few projects waiting on my next parts order; paying $8 shipping on a $1 part is a NO GO.

I'm interested to purchase an LTC1799 PCB in Europe.
So far I found this one: http://www.circuitbenders.co.uk/forsale/LTC/LTCPCB.html
Being new to such mods it is difficult for me to figure out if this is a fair deal, it does feel a bit pricy...
Any hints would be super appreciated!
Thanks
Looks like a good deal, completely assembled and ready to install.
