SY99 8MB Magic Memory Board is available!

Unread post by wohali »

WohMart.COM is proud to announce the Yamaha SY99 8MB Magic Memory Board (MMB) is now available!

This is an all-new designed-from-scratch 8 megabyte sample/MDR expansion board for the SY99. It installs under the bottom cover, and uses 2 of the connectors on the DM2 circuit board. It also needs 2 extra signals, taken from an IC on the board - so installation requires an intermediate level of technical skill (soldering to fine-pitch SMT ICs skills are necessary).

We will also be supplying upgrade EPROMs and CPUs if your SY99 needs them. Because blank CPUs are very hard to obtain, these do come at a premium price. If you already have v1.57 on your SY99, you only need our customised EPROM. Be sure to read the instructions on the order page carefully, and select the correct version when placing your order.

Full details, including installation instructions and the order page, are at https://www.wohmart.com/sy99-mmb.html . The first batch (extremely limited quantities) will be shipping next month. Batch 2 will ship early next year.

I'll be happy to answer any specific questions you may have here, or you can email us directly at support - at - wohmart - dot - com.

Special thanks go out to shadowmask (Brian @ Sector101), DrSynth, and Mark W. for their help in bringing this project to fruition.

Great News! How about shipping and customs? Is it included in the price indicated? I'm in Europe - am I guessing right that you'll be shipping from Canada?

Hi synthjoe! Shipping is a flat $20 USD regardless of destination, and shows up when you press the "Buy Now" button in the PayPal shopping cart. I do not pre-pay customs, so you'll have to settle that on your receiving end.

That's great new for all who put the effort into the project. Out of interest, how many were in the batch?

Thanks for sharing. That is a good number to start with. :)

Hopefully, sy.factory will be of some use in building the waves/samples for this. :)

Derek,

Abosultely! IMHO, having sy.factory is essential to management of your SY as a whole, not just for the samples!

The way it handles drag&drop/copy of patches makes it a breeze in assembling an 8MB "mega-bank" combining together your existing patches with custom samples.

Glad to hear it, Manny. :D

I just realised that I have a mail from you regarding sample keymaps, which I have not looked at yet. I am busy on kronos.factory right now, trying to get the first release out within the next week, but once that is done I have a batch of sy.factory tasks to look at for the next release.

HI everyone,

Batch 2 of these boards is now available. For those who need them, I have enough CPUs for a handful more orders, with more blanks on the way shortly. (The CPUs are getting harder to find.)

Batch 2 includes a new revision of the PCB (v1.2) that uses improved connectors and cable harness, a switch to the more common CR2032 battery, and by popular demand, a mounting hole with screw and spacer supplied, so you can fasten the memory board to the SY99.

I just got a 99 today, so apologies for what must be an obvious question: What improvements are gained by adding more sample RAM? Are there any good resources that explain what a 99 loaded with RAM can do, vs a 99 with no extra RAM?

The SY99 lets you play back samples alongside its FM synthesis via the sample-based AWM2 synthesis engine. You can use samples from cards in the Waveform slot, or in RAM loaded from floppy disk, MIDI transfer, or copying off of a Waveform card (that is not copy protected).

More sample RAM gives you more samples, or bigger ones, plus you can apply some limited modifications to the samples in RAM. You only get 512KB of samples into an unexpanded SY99's RAM. That's not a lot; at grainy 8 kHz, only about 15 seconds.

This expansion gives you 8MB, and is battery-backed, so loaded samples stay across power off/on events. You can also use the RAM for MIDI Data Recording - aka the sequencer.

The Sector101 WaveBlade waveform card gives you access to 8MB of samples as well, but you need the programmer to change them, and this has to be done with the card out of the synth. If you have both the WaveBlade and Sample RAM, you can also copy the samples from the WaveBlade into the SY99 - accessing both sources at once. This gives you simultaneous access to potentially up to 16MB of samples! Depending on sample rate, this can be quite a lot of sampled audio.

Does that help?
