Samplers are really versatile devices but they are complicated too. All early samplers have their restrictions but also their benefits, so that it is a good idea to think about your Use-Cases for them. My personal Sampling Use-Cases are listed below. If you could access the sampler via a editor-software try this out ... it is not automatically a better or faster way to operate them in this way but it can be much more conveniant. So try it out and find or adjust your personal workflow.

I want to play sounds sampled from monophon devices polyphonically, or simply add velocity- or aftertouch-sensitivity to it.

That are mainly sounds I created on the Minimoog or the MS20. Both are monophon and don't have Keyboards that are Velocity- or Aftertouch sensitive. The main challenge for this Use-Case is that I want to create a lifelike imitation of the original sound that is playable over the whole Keyboard range. To reach this goal most of my really old samplers are not a good choice. The sampling Memories are pretty small so that, even if the sampling rates are high enough, the resulting sampling len is quite limited. Together with the need of taking more samples to cover the whole Keyboard these are unfavorable conditions.  The only sampler in my Studio that meets the requirements is the Roland S760, and therefore it is my choice for my Use-Case 1.

Roland S760 : Stereo 16Bit ADC, 18Bit DAC, up to 48kHz Sampling Rate, 32MB RAM, dynamic digital filter

I want to create new sounds that make use of the "flavour" that are created by the sampler itself.

Mainly the degration of Audio due to the sampling- or the note-stretching process creates this sought after magic. It could be also useful to refine the results with additional filtering and envelope control. This is a perfect Scenario for all of my other old school vintage samplers. Which Sampler I take depends on "what I want to create" and from the "characteristic of the sampling Signal".

Ensoniq Mirage : Mono 8 Bit ADC, Sampling Rate in 70 steps from 10 to 33kHz, 128kB RAM, dynamic analog LP filter with resonance

Prophet 2000   : Mono 12 Bit ADC, 16 31 and 42kHz Sampling Rate, 256kB RAM, dynamic analog LP filter with resonance
Roland S50     : Mono 12 Bit Resolution, 16 Bit ADC, 15 and 30kHz Sampling Rate, 750kB RAM, only static digital filter with resonance
Roland S330    : Mono 12 Bit Resolution, 16 Bit ADC, 15 and 30kHz Sampling Rate, 750kB RAM, dynamic digital filter with resonance
Akai S612      : Mono 12 Bit ADC, 4-8-16 and 32kHz Sampling Rate, 128kB RAM, dynamic analog lowpath filter without resonance

Prepare sampling :
- Switch P2000 on (internal sounds loaded during Startup)
- Switch off Preset Mode    press PRESET (PRESET Led is off afterwards)
- Delete all Samples        press SAMPLE, press 8, choose ALL, press EXECUTE

You could save this Setup as new "empty disk" but remember that only the samples are cleared. This is sufficient as a starting Point for my Workflow. If possible try to get the article "Keyboard-Clinic #8" from the Keyboard Magazine 10/1987. It describes, beside the sampling and mapping process, the creation of a "Null Disk" that prepare the P2000 for proper sampling.

Additional Infos about the sampling process :

The Sample Len must be given in memory blocks. Not upgraded P2000 devices had a memory of 256 kByte (= 256 x 1024 Byte = 262144 Byte), that are divided into 128 memory blocks which leads to a block size of 2kByte. Upgraded variants or the rack Version P2002 are equipped with 512 kByte of sample memory that are divided into 256 blocks. The maximum amount of memory are 1MByte.

The available Sample Len depends on the choosen sampling rate:
Rate      Maximum Sample Len in [s]
16kHz     16,384
31kHz     8,456
42kHz     6,241    

The choosen Samplerate also set the resulting playing range of the sample. I found this table in the user manual:
Rate      Lower Keys    root key     Upper Keys    Keyrange
16kHz     18            x            24            43    
31kHz     18            x            12            31
42kHz     23            x            7             31    

At my experience it depends also on the Firmware Version that is installed. After I upgraded to the last available Version 4.3b it ended like this:
Rate      Lower Keys    root key     Upper Keys    Keyrange
16kHz     18            x            24            43    
31kHz     24            x            12            37
42kHz     24            x            7             32   

The sampling process itself is easy. The main reason is that you need only one single sample to get instantly a playable Sound over the whole S50 Keyboard … no mapping necessary. If you stretch and slow down one sample over such a wide range, then Audio degrading is more or less part of the result. But hey … this is exactly what we want from our vintage samplers, isn't it ?

Similar to the Roland S330 I'm using monitor and mouse to operate the Roland S760. Because of it's graphic Display it is possible to work without these tools. But, referring to my age, it is much easier for me to use the bigger monitor display :o)

Sampling a single sample  :
- prepare Quick-Sampling  : choose "PATCH" and command "QUICK SAMPLING"
- open screen Keyboard    : right-Click "little square on the left side of the Patch Number field".
- name the Patch          : input Name and click "CR"
- define sample parameter : click "SMPLING" command and define your sampling parameters
- check level             : play source and check or correct the recording level, then click "READY" command
- start sampling          : click "START" command, and play source

Looping :
- prepare looping         : click "LOOP" command
- define loop parameter   : set Loop-Mode, set "LOOP"- and "END"- values to define the loop, then click Exit
- end Looping             : click "END" command if you reach a satisfying loop

Mapping :

- prepare mapping         : choose "PARTIAL" and command "COMMON". Be sure that the partial-name is equal

- set map                 : change "LP" and "UP" On the Partial List to specify the mapping range and click SET

Sampling on the Mirage is very special ! The two Digit User-Interface is quite challenging same for the process to create clean loops. The main goal is to choose a combination of sampling frequency and sampled note that creates complete wavecycles within one of the Mirages Memory pages of 256 Bytes. If so, you can setup a loop over one full memory page. That won't overload the rusty CPU and Q-Chip within the Mirage and result in a clean click-free loop.

To reach that Goal you have to choose the best sampling frequency for a note that you would like to sample. Even if you do so, it never matches perfectly. It is more or less a approximation that don't fulfill the goal exactly. One way to deal with this fact is to prepare the sampling Signal before the sampling take place ... f.e. you could record the sampling source first and Playback at a different pitch.

Or you try to find the best approximation between a sampling frequency and a note ... and live with the result. That is my preferred way ... after some research I found two combinations that worked for me :o)

The S612 Sampler is very easy to use, what is a result of it's limited design and his analog user interface. But beside all of its limitations it has one great advantage ... nearly everything that you sample with this machine sounds instantly good and lovely ;o)

Even today (in 2025) it isn't a forgotten piece of hardware because you can upgrade it with some useful extensions from D.A.Wilson from "Hideaway Studio". My personal S612 arrived with a defective slider and a uninstalled FPA-Extension (Front Panel Animator). After repairing I add a really useful XD280 extension from Hideaway Studio, which is a modded gotek usb floppy adapter with a custom interface board. It is a replacement for the MD280 Quick Disk Unit. You can find a repair story together with some background information about a alternative Firmware V1.3e, that made my personal unit so special, on my old website :o) --> S612 restoration  

Prepare sampling :
- Select Sample Rate  : play one note C2-B2 for 4kHz,

                        play one note C3-B3 for 8kHz,

                        play one note C4-B4 for 16kHz,

                        play one note C5-B5 for 32kHz.
- Adjust Rec-Level    : play Source Signal and adjust Rec Level Pot (set to 0dB to +3dB for clean Signals)

Sampling :
- Start Auto Record   : press NEW, NEW-LED is switched on … the S612 now waits for a proper Input signal      
- Play note           : this starts the recording, the NEW-LED flashes during recording
- Hold the key        : until NEW-LED stops flashing, and is off again

You can overdub the already recorded sample as many times you like, simply choose OVERDUB instead of NEW. This is a really cool and easy to use feature of the S612 that I haven't seen on another machine. Keep an eye on your recording levels if you plan to overdub your sample. Be sure to keep them low enough to avoid clipping and have fun with that nice function !!!

Looping :
- Switch from ONE SHOT mode to LOOPING or ALTERNATING mode
- Adjust Loop with START/SPLICE slider and END slider

VCA Decay :
- Set Decay Pot to adjust the note sustain

Filter Cutoff :
- Set FILTER Pot to adjust the cutoff frequency. It's a static setting because the S612 supports no Envelopes.

Vibrato :
- Set SPEED Pot to adjust the Vibrato speed
- Set DEPTH Pot to adjust the Vibrato depth
- Set DELAY Pot to adjust the Vibrato delay

Storing :
- Prepare storing     : insert formatted disk or Change HXC Image on your XD280 Emulator.
- Storing             : press SAVE, display shows flashing "d", press SAVE again to start the store process.
