Select a kit

A kit is a group of 4 samples.

Kits are organized in 26 banks (A to Z). Each bank includes up to 100 kits:
  • A0 to A99
  • B0 to B99
  • ...
  • Z0 to Z99

Rotate the encoder to display the current kit and to select a kit, and load it by pressing the encoder.

You can only scroll through created kits inside the SD card.

Fast scroll (bank select): hold  assign  and rotate the encoder.

When selecting a kit, pressing ① ② ③ or ④ will display the name of the sample on the screen.

Trig a sample

Use the gate input 1 to play SP1 (sample 1), gate input 2 to play SP2, gate input 3 to play SP3, gate input 4 to play SP4.

You can see the samples playing on the screen, thanks to the 4 vu-meters:

Each sample is always outputted on its dedicated audio output (1, 2, 3, 4) and unplugged audio outputs are normalled to "mix" output.

To pre-listen a sample, hold  listen  and press the mode buttons ① ② ③ or ④.

Double press  listen  to stop all samples.

Press  listen  to quit the current mode (kit select, assign mode, settings, ...).
Assign a CV input
Each of the 4 CV inputs can be assigned to any effect/parameter of any voice:
  • press  assign ,
  • select the CV input (►1, ►2, ►3, ►4)
  • select the sample(s) to control (SP1, SP2, SP3, SP4, ALL SAMPLES)
  • select the effect/parameter to assign (pitch, bits, filter, freeze, start, length, env, run, levels, layers, trig freeze)
Mute groups
Mute groups allow each sample to be muted by one or more samples, very handy to create open/close and conditional behaviors. While holding  assign , select the sample to be group-muted (by pressing ① ② ③ or ④) and then select the sample triggering the mute (up to 3 samples).

Let's take a few examples:
  • SP1 muted by SP2
    hold  assign , press ①, ②, release  assign 
  • SP2 muted by SP1 + SP4
    hold  assign , press ②, ① , ④, release  assign 
  • Delete SP1 mute group
    hold  assign , press ①, release  assign 
Press  assign , release it, then press ① ② ③ or ④ to enter the layers mode: the screen displays the running layer of the voice.

 NEW !  Press once again ① ② ③ or ④ to enter the per voice layer playback mode (manual, random, cyclic, ...) of the currently selected voice.

 TIP  If the "LAYERS" setting is set to "MANUAL", you can manually select the layer with the main encoder. Press the encoder to listen to the selected layer while scrolling through them.
We strongly advise to use only the provided microSD card, as its fastness is fundamental for Rample optimal playback. We do not guarantee Rample stability with other cards.

Please do not eject the SD card while Rample is powered.

If you ever need to reformat your SD card, we strongly encourage you to use the official SD Memory Card Formatter from the SD Association, as it can dramatically improve the card's performance compared to other formatters.
Audio effects & parameters workflow
Each voice has its own “rack” of effects, and all audio effects can be enabled at the same time, allowing you to manipulate your samples in real time, from a gentle lowpass to a massive destruction!

Each potentiometer controls the selected effect amount, per voice. Pot 1 will always control SP1, Pot 2 will control SP2, ...

Rotate a potentiometer (or select an effect with ① ② ③ or ④) to display the '4-voice effect values' view:

Audio effects

Select an audio effect (pitch, bits, filter, freeze) with ① ② ③ or ④.

pitch — a great sounding pitch engine, based on a 6-pole interpolator. The range goes from -1octave to +1octave:
bits — two different bitcrushing algorithms, based on sample rate reduction and resolution reduction. It produces distortion and warms up the audio signal:
filter — a low resonance filter, DJ-style, cutting off the high frequencies (low pass) or the low frequencies (high pass):

freeze — when enabled (pot ≠ midpoint), Rample will sample and loop a fraction of the played waveform, creating a glitching effect:

NOTE: Uniquely to the freeze effect, you can activate/deactive the effect independently of the amount, by assigning a CV input to "TRIG FREEZE".

levels (hold  assign  and press  listen ) — turn the knob to the left to decrease the voice gain, or turn to the right to drive the signal:

 TIP  edit the 4-voice values at the same time by holding an effect button and rotating the menu encoder (e.g. hold PITCH + rotate encoder).
Advanced parameters

Double tap ① ② ③ or ④ to select start point, length, env or run mode.

start point — set the beginning of the sample playback.
If setting SLICER = FREE, the start point goes from 0% to 100% of the sample total length. If SLICER is set to a value (/8, /16, /32, /64, /12, /24, /48), the sample length is divided by this value into equal parts, handy to edit the start point of your sample 'in beats'.
length — Set the duration of the sample. Depending on the setting SLICER = FREE, the duration goes from 100% to 0% of the sample total length. If SLICER is set to a value (/8, /16, /32, /64, /12, /24, /48), the sample length is divided by this value into equal parts, handy to edit the length of your sample 'in beats'.

env — turn the knob to the left to add sample attack,
or turn to the right to add sample decay.

run mode — 3 types of sample playback.
- one shot: a trig plays the sample entirely
- toggle loop: a trig alternatively plays/stops the sample
- gate high only: sample played only when gate is high

Momentary effects

Press and hold ① ② ③ or ④ to access the effect in "momentary mode". While holding, you can play with an effect parameter knob to change the sound, however the effect will be set back to its original value after releasing ① ② ③ or ④.

In "momentary mode", turning the main encoder will affect all four voices. Pressing the encoder applies the momentary parameters.

Note about start point & sample length

Using 'start points' and 'length' parameters is a great way to slice your samples and play a controlled part of the waveform:

Slicer: start point & sample length

The example above shows a sample divided into 16 equal parts (setting SLICER = /16). With the SLICER setting, it's possible to increase/decrease this number of equal parts.

Awesome when playing with drum loops or organized samples in a single .wav file!

How to make your own sample kits
The rule is simple: 1 kit = 1 folder. Inside the Rample SD card, each kit must be in a folder named ?X where:
? is the bank letter, from A to Z (handy for organizing your samples)
X is the number of the kit, from 0 to 99

In a folder, drop your favorite samples. The first character must be the number of the voice, from 1 to 4 (voice 1 to voice 4). For clearer file names and easy sorting,you can add any text after the digit, as per the figure below :

These files must be in a standard .wav mono format, 16-bit or 8-bit, 44100 Hz, minimum length 50ms. There is no size or duration limits, you can even play hours-long samples.

You can drop stereo samples in your kits. Rules are the same as for mono samples. A stereo sample will fill 2 mono voices.

 TIP  Any wave file editor software should works (like Ableton or MediaHuman converter).
Multi-layers kits
It's possible to "multisample" your kits: in a folder, add up to 12 samples per voice.

These layers can be played manualy, randomly (by default), Round-Robin (cyclic), or controlled by velocity midi in.

 TIP  MANUAL layer mode allows you to choose which layer you want to play. Press  assign  then press ① ② ③ or ④ to enter the layers mode. Scroll among them using the main encoder.

The following example shows SP1 with 5 layers, SP2 with 2 layers, SP3 and SP4 with only one layer :

Sample layer names are numerically and alphabetically sorted in Rample, handy to create a special order when controlling the layers with midi velocity or CV (first samples are triggered by lowest velocities).

 TIP  Stereo samples can also be layered. All layers must be of the same type (mono OR stereo) in a voice.
To enter the setting list, simply press the menu encoder:

reset all effect parameters to default.

randomize effect values.
