Akai S612 sampler

I opened my newly acquired Akai S612..to check for spiders and animal residue from its previous owner – i was intrigued by the “cassette interface”. Mine was screwed behind a closed metal door.

I realized right away it is the same cassette port as the Commodore 64.

And yes, you can save, verify and load your samples using an old (non)trusty tape Datassette!

I sampled a sound, got some tape to record, went fast forward 004 counts on the tape counter, pressed rec and play and then pressed save on the Akai panel. Red light, it’s recording.

Counter reading 044, the Datassette automatically stopped. I rewound the tape, switched off the Akai (remember with these old machines it is better to switch them off before plugging or unplugging devices from serial ports..), on again and Load. Pressed play on tape, and yes. It’s working. Easy.

No need to buy the MD280 rack to load discs on the S612.. you just need a Commodore Datassette (clean its heads and fix azimuth before doing anything)!

MAM/FAT 383/FREEBASS 303 simulator guts

A couple of gutshots of the 303 simulator (cannot call it clone since it doesnt have a BA662a..)..

Some kosher transistors (1583, 2291) but most of them are just 2N3904.

Sounds quite good.. i remember staring at the Turnkeys window in Charing Cross Road (98?) when these came out, along with FAT’s other offerings, rebadged MAM, like the cool resinator (the resonator) and some other rack in sexy colors!

Creating a drum program on the Akai S900

Ok this is as basic as it gets, but still it’s nowhere to be found on the actual Akai S900 manual, since it deals mostly with pitched sounds and how to spread them on the keyboard.

How do you make a drum program from recorded samples on the Akai S900, and play those sounds from a controller in midi in?

Well, first of all you must understand what a keygroup is.

The keygroup is the number of samples in the program. Or something like that.


Here the guide, how you do it, step by step:

-press the function button sample rec, press “letter” function and enter the name of the new sample, scroll down and set the sample rate: choose 16000 for best definition (it will be punchy nevertheless) then scroll the page down until you can assing that specific sample to a key on the keyboard- I normally start from A1. For easier operation, use a keyboard plugged in the midi in port.

-record sample.

-press edit sample function, since they are drum samples you dont want any scaling of the single hits so deactivate any transpose function, then set the sample start and end points.

Scroll the page down and choose (right arrow twice) to discard whatever is before the start and after the end points (aka sample truncate).

-press edit program and choose (right arrow) the name of the sample you just recorded.

At Program screen 03, KEYGROUP,  add one more keygroup to the total keygroups by pressing + on the COPY line. Then scroll page down, assign the keygroup to the sample you just edited, and set the sample pitch range-since it is a drum sample, you want the range to be of just one key, so set it to the key you assigned upon recording for both range figures. If you assign it to another key, the sample’s pitch will be affected. You will not be able to listen to the sample as you do this so make sure you write down what note the sample was assigned to.

-press save, scroll down page to (right arrow twice) save prg and samples.

That’s it, plain and simple, easy guide to make drum programs on this legendary sampler.

Remember to drive the inputs a bit when recording-i always record at 16000 (best quality) but sometimes in a drum kit i like to have also low fidelity drum hits, so i record also some kicks and snares at like 8000-they add some dirt, just dropping them in the pattern, they add character.

Akai S900 disk drive replacement

Since keeping it strictly old school is a must, i decided NOT to go the Gotek/ HxC floppy drive emulation route to make up for my S900’s broken floppy disk drive.

Which disk drives can be used to replace the Akai S900 floppy drive? Theres a page on gearsluts with a few suggestions, but i felt the info was a bit messy and not really clear (a few yes this works, some no-nos etc).

I took an old amiga 500 external floppy disk drive and yes it works on the akai S900-just be careful about the header’s orientation. It is a drop in replacement. It can format and use modern HD floppy disks too.

So in a nutshell: amiga 500 floppy disk drives can work as a replacement for the Akai S900 sampler.

Just a piece of info from Masu.

Roland TR-505 stuff

Points for individual outs (audio signals-add ground from ground point)


Ground

Points for bit-crushing effects: just solder to leads and strike them against the other at pleasure.. i dont like bending stuff, but this is the way it came when i bought it second hand..

I bought a ROM expansion that adda DMX, LINN DRUM and LN1 sound samples.

Desolder IC11


Solder the ic socket


Solder the switch to the pcb



All done! 

You can buy the expansion here:
