Homebrew VFX cartridges

Re: Homebrew VFX cartridges.. PCB?

2016-10-29 by koknbull2@...

Very interesting, I've been wanting a RAM cart for my SD1 for years until I found a genuine RAM cart online (Stor-Cart 32) - but now as this PCB exisits I could be interested if the PCB is available for purchase which is where all the time and effort goes.
Just a word of caution, there cart PCB for the ESQ1 looks the same except the two are different, the ESQ1 takes a 64k chip and as you say this VFX/SD is the 256k device.

Yeh there would be two options; either photoshop the board scans to 
something that's good for exposing a pcb, or use the scans to make a 
proper schematic & board layout with some pcb design software and then 
have some shop like OshPark manufacture the boards.

If ESQ1 cart is 64k (and it's cart slot is VFX compatible), I suppose 
that to use this cart you would need to ground address pins A13 & A14. 
Or perhaps add switches (toggle +5V / GND) to these pins to have 4*64k 
banks to select from.. But do take this with a grain of salt, I don't 
really know a thing about the ESQ1. I'm just assuming that the designs 
would be close to one another since both are about from the same era :)

I have a couple of VFX RAM carts that I've converted from ROM carts 
which had been demo carts. If you need one or two just let me know what 
you think it's worth.

if you have a PCB you still wont have a nice housing...

Ehh, those housings can be 3d printed in small runs, or in large runs you could have them made.

Re: Homebrew VFX cartridges

2016-10-30 by koknbull2@...

yeh that nice housing (box) stopped me making a ton of these many years back. I did look around and thought up alternative designs but as always, the cost of that item alone was more than everything else so I abandoned the idea. I have thought of using 3D printing but it all tends to take up so much time. Maybe nowerdays with modern manufacturing making the little boxes might be more affordable, but for proper ones including the mould I would still think is a huge amount of money. Has anyone looked into having the boxes made on a 100 off price?

Does anyone have a 3d model of the housing, for 3d printing or other manufacture?\

I've been toying with the idea of going somewhat overboard, and build a cartridge that uses an SRAM in place of the EEPROM, and additionally has a microcontroller and a large flash memory: such that the cartridge always remains in place, powering the SRAM and microcontroller, and that "ejecting" the cartridge would be done by tristating the cartridge-detection pin (and the rest of the cartridge bus except for power and ground). The microcontroller would read from one 'slot' in the large flash memory to the SRAM or write from SRAM to a flash 'slot' while in disconnected mode, effectively providing a single, software-switched, multi-cartridge.

But that would probably be just a tad excessive :)

A writable multi-cartridge for a VFX would require an EEPROM compatible with but significantly larger than the 28C256, and I haven't had a huge amount of luck finding any that are more than 1 Mbit (such as the Atmel AT28C010) which would correspond to 4 plain cartridges - and thus not a huge advantage over 4 separate cartridges. With a buffering SRAM (that the VFX reads&writes) and a microcontroller that shuffles the data to&from a much larger Flash memory, things are not limited by existing EEPROM sizes, and that also allows using serial flash memory chips that are quite compact.​ Or it would allow creating a cartridge with an ESP microcontroller that would allow WiFi access to the cartridge (which would be rather cool actually, but even more over-the-top) :)

Interesting. But if it's not so much about having thousands of sounds 
available in real time you might remember this page:
http://hxc2001.free.fr/floppy_drive_emulator/
which solves the unfamous 'my floppy drive died and I cannot find a 
Shugart drive' problem and provides plenty space for sounds.

2016-10-30 by Christian Brunschen

I've already investigated the floppy emulators :) But one of those gives a replacement for a floppy drive, not a cartridge; thus it applies to the VFX-SD, SD-1 and SD-1/32, but adds nothing to the plain VFX – that still has only the cartridge as an expansion mechanism.

Also, a cartridge does offer another separate bank of sounds & presets in addition to the INT and ROM banks, so allows 60 more sounds available to choose from at the touch of a a few buttons, which may be useful during a live performance.

Best wishes,

Re: [Ensoniq-VFX-SD] Re: Homebrew VFX cartridges.. PCB?

2016-10-31 by koknbull2@...

Some interesting ideas here. I think the best is just to keep it a standard ram-cart so not to get too distracted. I find it more useful to have a number of carts that I've programmed up, it sort of acts like a library. For example having 5 carts with different sound types, 3 with sound collections. I also use SoundDiver and use floppy storage both of which are very good, but for instant access, usualy for fast auditioning, carts are the way.

As an aside, when I take my SD-1 out the house (gig/rehersal) I always remove the cart as they get stolen.

Hi,

I was also looking into making custom cartridges. Until I got an offer on Gotek floppy emulators with the HxC firmware - having a 1000 floppys in a floppydrives space (well, on a USB stick) is really comfortable. And likely cheaper than cartridges :)

Hey All,

My 15 yr old son has gotten a VFX-SD and uses it for his band. I found and downloaded the manual, but it's difficult to understand for him.  He's looking for a good B-3 sound. Does anyone have it and can tell him how to load it?  Also, is there anyone who could possibly Skype with him and give him a basic primer on using the functions of his keyboard?  I appreciate  any n all help he can get. Thanks!

Hi, Jim,

There's a factory patch called "Organizer" (as I recall) that has a pretty good Hammond simulation.  This is in the SD-1 32 voice library.  You can control the Leslie speed with the mod wheel, although when I used it on stage I had a MIDI foot controller to keep both hands free.

If you have this patch you'll find it useful.  

Best,

Bill

There's a set of patches you can download from http://rhythm-lab.com/ensoniq-vfx-sd-patches/ . this will give you a zip file with both seveal entire sound banks and a lot of individual patches in ".syx" format, which is MIDI System Exclusive aka "sysex".

You should be able to send these from any computer over MIDI to the keyboard; if your computer doesn't have a built-in MIDI interface, you should be able to search for "usb midi cable" or "usb midi adapter" and find an inexpensive one that should be more than good enough.

To actually send the files to the keyboard over MIDI, you'll need software like MIDIOX for Windows or SysEx Librarian for macOS that can send (and receive) sysex files.

Best wishes,

Hi Jim,

I would be happy to Skype with your son, I'm very familiar with the in's and out's of the VFX-SD. I can
give him a crash course in what the instrument can do, how things are organized, where to find things in the manual, There are several good organ patches that come stock, and the instrument is fully programmable, it's pretty quick and easy to tweak the OEM patches to get the sound he's after.

You can email me directly at danrue@hotmail.com to setup a time,etc.
