Erica Synths Sample Drum Cheat Sheet

Overview

Dual-channel, performance-focused sample player. Each channel is independently addressable and features: - Fast sample playback and triggering - Live and auto/manual slicing - Extensive CV assignment - FX and envelopes per channel - Sample recording and trimming - Project memory

Front Panel Controls & Features

Control/Jack	Description
A/DATA	Main data/selection encoder (push to confirm/select)
B, C, D/BACK, E, F	Context-sensitive encoders (see menus/functions below). D/BACK: also acts as a back/return button.
TRG1/PLAY	Manual Trigger button Ch1 (Performance mode only); preview sample
TRG2/SHIFT	Manual Trigger button Ch2; also SHIFT for accessing secondary functions; preview waveform/sample info
OLED Screen	Visual feedback, waveforms, menues, scopes
**SD Card Slot	For sample/projects management (microSD, must keep directory structure as specified)
CH1/CH2 Toggle	Select which channel (for sample loading/editing/assign)

Input/Output Jack Summary

I/O	Function	Voltage Range
TRIG 1, 2	Trigger Inputs (Ch1 & Ch2 sample playback)
CV1, CV2, CV3 (x2)	3 Assignable CV per Channel: tune/sample/start/end/loop/slice FX/env, etc. CV3 on CH2 used for sample recording	Configurable: -5V to +5V -10V to +10V 0V to +5V 0V to +10V 1V/Oct (no depth setting)
OUT 1, 2	Individual Channel Audio Outputs	10V ptp max (settable via menu)
SD	MicroSD slot for samples/projects
Power	Standard Eurorack header (65mA @ +12V, 2mA @ -12V)

Top-Level Workflow

1. Loading Samples

Prepare mono 16-bit, 48kHz (or lower) WAVs, store in SAMPLES folder on SD card.
In LIBRARY Menu, select samples with A/DATA encoder; push to upload to RAM.
Preview with TRG1/PLAY (audio), TRG2/SHIFT (waveform/size).

2. Sample Editing (SAMPLE Menu)

Access playback start, loop, end; play direction/mode (forward, backward, looping).
Assign tuning (supports proper 1V/Oct).
Enter slicing (auto: linear/zero-cross; or manual with ADD/REMOVE slices).
Slices: up to 32 per sample; playback modes: FWD, BKW, RND, CV, NONE.
Adjust envelope: attack, hold, decay (time & shape); Short/Mid/Long/Relative scaling.

3. Recording Samples

In LIBRARY menu, select RECORD for sample input via CV3 (CH2).
Set input RANGE, LEVEL, and THRESHOLD.
48kHz, 12-bit ADC, 30 sec max.
Trim edit, slice and save to SD.

4. CV Assignment

Assign any CV input on each channel to nearly any parameter (tune, playback mode, start, end, envelope stages/shape, FX params, slice, etc.).
Set CV input range:
-5V/+5V (default, most LFOs)
-10V/+10V
0/+5V (for sequenced sources)
0/+10V (envelopes)
1V/Oct (for pitch/slice/sample)
Assign depth for mod destinations. View incoming signals on scope.

5. FX

Delay, Reverb, Lowpass/Highpass, Bitcrush, Fold, Drive (per channel).
3 parameters each, CV-assignable.

6. Performance Menu

Assign 6 main encoders (A–F) to instantly tweak any assignable parameter per channel.
Encoders: A/B/C for Ch1, D/E/F for Ch2.

7. Projects & Settings

Save all settings (samples, edits, FX, CV, encoder assignments) as Projects (Single: one channel, Double: both).
Recall instantly for performance. Double loads interrupt playback.
Update system, adjust output levels, display settings, and trigger delays in SETTINGS.

Quick Reference

KNOBS/ENCODERS

A/DATA: select, confirm, menu navigate (push to enter).
B/C/D/E/F: context: start/loop/end/slice/fx/env/assign CV parameters, etc.
D/BACK: "return/back" to previous screen.

BUTTONS

TRG1/PLAY: Manual trig Ch1.
TRG2/SHIFT: Manual trig Ch2 or SHIFT (hold).
CH1/CH2 Toggle Switch: Select channel for edit/load/assign.

INPUT JACKS
