Yamaha RX7 complete sample pack

Yamaha rx7

RX7, 12bit drum machine from Yamaha (1987) comes after RX5. It has all RX5 waveforms + even some more but it does not have individual outputs and lacks some less important features. Keys are pressure sensitive.

Samples were originally recorded at 24bit 48khz. For recording I used Lexicon mpx550 (bypass mode). Converted to 16bit without noise dithering.

These samples can be used with no restrictions as components of musical compositions either private or commercial.

Akai s3000xl scsi to ide cf mod

Here are pictures of my S3000XL with cf card inside as hard disk.
I used IO-Data scsi to ide adapter from ebay, Ide to cf adapter, 2gb sandisk card, and some molex cables.
I mounted IDE-to-CF adapter on the bottom by using 3 screws. It fits perfect
I also modded power plug as you can see on the picture to get 5v and 12v.
I have 16 partitions, about 500mb available.

Akai s1100 CF card inside (scsi to ide)

I wanted to have hard disk inside my s1100. Real hard drives are not recommended due to risk of overheating. S1100 produces high temperature inside already.

Take a look (click for bigger pictures):

There is second power socket on the main board, the same as for floppy drive, so its easy to make power cable for scsi adapter.

I bought:
1) scsi 68pin to ide adapter (ebay)
2) 68 pin internal cable (ebay)
3) 50-68pin sci adapter (ebay)
4) ide cf adapter (ebay)
5) two cheap metal holders (local store)
6) molex cables (ebay)
6) compact flash card (local store)

Important thing: Internal scsi socket in s1100 and s1000 is probably wrong, i don’t know why, maybe hardware bug.
If your scsi device won’t work, try plug socket in backwards!
So cutting or filing cable plug may be necessary.
I’ve cut 50 to 68 adapter to fit backwards.

I have about 520mb space available which is max for s1000/s1100 and max 17 partitions.

I tired few CF cards and only two works: Transcend 1gb and Pretec 16gb. Sandiks, Kingston cards were not recognized.

Now it works perfect. Any questions?, please leave comment. Thanks!

editor for windows

Here you have complete drum and fx waveform pack from Roland MC-505 Groovebox (1998-2002).

Samples were recorded @ 96k 24bit thru EMU 0404 pci soundcard, with max possible signal level.
Then normalized, denoised, resampled to 44khz 16bit and trimed.
No internal effects were used.
Overall quality is the best you can get. MC 505 internal waveforms are just up to 32khz.

These samples can be used with no restrictions as components of musical compositions
either private or commercial.

Convert samples to 10bit 11bit 12bit 13bit

convert samples to 10-13bit

I made few useful scripts for converting wav samples to 10-13bit. Windows only!

You need sox command line converter.
Download and unpack to C:
Download archive with *.bat scripts

You can use scripts in two ways.
First: Open internet explorer, type “shell:sendto” in address bar. Copy scripts to this window. Now you can click on yor wav file(s) right mouse button and simple send to selected script from “send to” menu.
Second: Simple drag and drop wav file(s) to script icon.

Converted samples are located in /converted/ directory where your wavs are located.
You can send to script max about 30 files at once.

Scripts do not add any noise dithering.

10 bits – cuts signal below 60db
11 bits – cuts signal below 66db
12 bits – cuts signal below 72db
13 bits – cuts signal below 78db

Enjoy! :)

Yamaha A4000 / A5000

Yamaha a5000

Very nice piece of vintage gear :) This is probably the most powerful and advanced hardware sampler. It has so many possible modulations, parameters to choose and it has great midi implementation. 24 bit DA, 20 bit AD, 128voices of polyphony, 6 powerful fx blocks + many different great filters, up to 128 MB of waveform memory (expandable by 72pinn simms). The little brother A4000 has 64voices and 3 fx blocks. You can use IDE or SCSI hard disks and drives. A5000/A4000 can read cd-roms or floppys from akai S-series, yamaha tx16w, E-mu EIIIx and Roland S-760. Imported data includes keymapping and looping only. You can import wavs or aiffs from fat32 (Windows) drives also. Unfortunately there is no software that converts different format programs to yamaha. But! you can use AWave or Chickensys Translator for reading or just load akai disks.

Very nice feature is that you can use a4000 as realtime FX processor, 3fx or 6fx (a5000) at once!
FX list is huge, very good and unique effects. You can route FXs to any output. For example You can send one FX to main out, second to digital out, and third to sub out :)

28.10.20015 update:
I found some stupid limitations. For example. You can’t set panning by key.
Even Akai s1000 had this feature. There is control key to pan function, but it pans whole channel not individual notes.
Second limitation is filesystem blocks. Even if you have 8gigabytes hard drive you can have only 8 partition max.
Every partition has limit of volumes and files. You can’t use whole space for many samples, you will fill all available blocks very fast.
So you can’t use 8gigs of space. You can’t transfer all content from factory cd-roms to internal harddrive.

The best solution is to have scsi CF reader and few 1-2gb cards for all factory samples.
Loading samples from cd-rom is very slow so its much better to load it from harddrive or cf card.
IDE CF readers do not work in most cases because Yamaha is very picky about cf-cards connected to IDE port :)
But i found that industrial Wd Silicon Drive II 2GB works.

Akai S5000 / S6000

Akai S5000

S5000 is my second favorite sampler. It sounds excellent, very clean and polished. Filters are not very aggressive or spectacular (however with resonance), but you get many types to choose (26 types). Good midi implementation, two lfos with many different waves. It has 64 voices of polyphony (s6000 has 128), max 256mb of memory (by using cheap 72pin simms). Very easy to edit, big screen, you can even plug ps2 keyboard. It accepts scsi removable drives and hard disks. You can get optional usb card for transferring and editing samples. S5000 can read *.wav samples and fat32 disks so even without usb card transfer from computer to S5000 is simple and easy. S5000 *.akp format is very popular, all sample converters can convert to akp. For example ChickenSys Translator or AWave which can even create and edit programs. All you need for transfer without usb card is removable drive in your pc (usb or ide) and second scsi removable drive in akai. Personally i use 2gb scsi jazz drives, but you can use more popular zip drives. S5000 is cheap, you can get it for max 200 pounds ($300). There is optional multi fx board eb20, but honestly… effects sounds very cheap… I prefer effects on old S1100. S5000 has additional 8 outs so you can use external effects (i recommend this).

Akai S3000XL

Akai S3000XL

Akai s3000xl is solid working horse, very popular. It has 12db low-pass filter with resonance, digital outputs, 32mb of ram expandable by cheap 72pin simms, 32 voices of polyphony, decent midi implementation, nice free windows scsi editor – MESA. You can get optional eb16 multi fx board and IB-304F filter board. Filter board adds band-pass, hi-pass or additional low-pass filter + eqalizer. S3000XL can read floppy disks from s900 s950 and s1000/s1100.

Akai S1000 / S1100

Akai S1000

have an S1100 unit. It’s my favorite sampler because of its bright, clear, and good sound and its nice 18dB filter. The FX board is based on the Motorola DSP 56000 chip, which is also a plus. I like the S1100 even more than the S3000XL. However, its MIDI implementation is very limited and it only has 16 voices of polyphony, with no resonance.

If you’re considering getting the S1000, I would recommend getting the S1100 instead. It has onboard digital output, FX unit, and SCSI ports, and it’s faster with louder outputs due to its 20-bit converters (while the samples are still 16-bit).

The latest OS for the S1000 is 4.40, which can be found here /files/akai_s1000/, and for the S11000, it’s 4.30, which can be found here /files/akai_s1000/

Please note that this OS can only be written to a floppy disk if you have an internal floppy drive in your Windows PC. It works only with the old DOS system, and won’t work on Windows. However, I have a few instructions on how to save it to a floppy disk:

  • First, download the Windows 98 boot disk from and save it to a blank floppy by executing the downloaded file.
  • Next, unzip the Akai OS .exe file and move it to the boot disk.
  • Restart your computer and boot from the disk, then run the OS .exe file by typing its name.

Update 17 Dec 2013:
I just found similar tutorial how to put cf inside akai s1100 at Mike Bass Page:

Update 20 April 2014:
I am still amazed by this sampler. I was preparing a library of old-school 8-bit samples from Fairlight CMI, Amiga, Atari, etc. and I can’t believe how these old 10-20kHz samples sound so beautiful on this sampler. The difference in sound between computer programs and this beast is huge.

I was curious about the secret behind this sampler, so I asked Uncle Google what made this piece of old hardware special. After many hours of research, I finally found the answer. It’s the “eight-point windowed sinc interpolation.” Only the S1000 and S1100 samplers use this method. Later Akai units, such as the S3000, use simple linear interpolation, and samples, especially those with a lower frequency than the native (44.1kHz), sound dull and have stronger antialiasing. This eight-point windowed sinc interpolation requires a lot of CPU power, which is why the S1000 only has 16 audio channels and needs more huge expanders.

This was very expensive, so for economic reasons, it was the last sampler with such a beautiful sound.

I also discovered something interesting. When you play a distorted sample (saturated, squashed or clipped), this interpolation tries to reproduce the lost signal and produces even more high tones from a lo-fi saturated sample. This is incredible. I noticed this when I loaded some old lo-fi snare and hi-hat samples with maxed levels and noticed unnatural high clipping.

Now I know why, because of its unique interpolation. It tries to reproduce lost tones. The signal is just interpolated beyond the 16-bit scale and clips. In this situation, the samples need some headroom. This is independent of the gain and volume settings. The sampler just needs the samples to be 0.5-1 dB quieter than the max level because it generates and adds high tones that the sample normally doesn’t have. A 20kHz sample is interpolated and sounds like a 30kHz sample! I don’t know how it works, but it sounds amazing.

If you want to use low-frequency samples in modern DAWs or software samplers, you need exciters, EQ, and other processing for good sound. But your Akai S1000 plays it better without any additional tweaking.

The S1000/S1100 are worth every penny. I am think it’s the best sampler for playing samples.
