Thank you for your interest in our new product!
As we are still working on the functionality, things often change and it is too early to write it all down.
The detailed manual will be ready in a few weeks.

For now, here is a short explanation and preview of commands, effects and options that will be supported by the user interface.

The pads in the top row are marked as:

SND TRK KEY PAT [-] -STEP/BPM+ WF MD RD WR 

These codes stand for (if there are alternatives, they are active depending on context):

Sound, Track, Key, Patch/Pattern, [Rest], minus/STEP/BPM/plus, Waveform, Mode/Modulator, Read, Write

The pads in the bottom row are marked as:

1   2   3   4   5   6   7   8   9   0   X   Y

These numbers are used to enter parameters (following a command composed using other pads) for example:

load patch #1: PAT & 1
store patch #2: WR & PAT & 2
stop arpeggiator: ARP & [-]
change key: KEY & +/-
change octave: KEY & UP/DN
change scale mode to one of the 7 basic modes: MD & 1...7
change waveform to noise: WF & X

the 12 pads on the right side are marked as:

AR 
CV
DL
EG
FT
SQ

This allows to select a command, effect or option using two-letter (or for less frequent / more dangerous commands, longer) codes.
For example if you click on two adjacent pads, you get:

AR: arpeggiator 
CV: control voltage
DL: delay
EG: engine
FT: filter
SQ: sequencer 

of course many other combinations are possible, here is a (in-)complete list:

AC: ACcelerometer 
AR: ARpeggiator 

CAL: CALibrate
CARD: SD card utilities (e.g. recites info about free space left on the SD card)
CFG: ConFiGure
CL: CLear/CanceL
CR: bit CRusher 
CT: Click Track
CV: Control Voltage

C0: Click Feedback Off
C1: Click Feedback On

DF: DiFfuser 
DL: DeLay 
DT: DeleTe
DR: overDRive

ED: EDit
EF: EFfect
EG: EnGine 
ER: ERase
ES: Edit Sample
EQ: EQualizer 
EV: EnVelope

FACTRST: factory reset
FL: FLanger
FT: FilTer 
FR: FoRmant
FS: FilterSweep
FQ: FreQuency

GE: Global Effect
GT: GeneraTe
GL: GLitch 
GR: GRanular
GS: GliSsando

QA: QuAntize
Q: Question (invokes audible explanation of how to use a certain command)

RD: RanDom
RE: REpeat
REC: RECord 
RG: RinGmod 
RST: ReSeT
RT: RoboTize (Exterminate! Exterminate!)
RV: ReVerb 

SAL: SAmples Lookup (tells information about directory containing samples)
SAD: SAmples Directory (selects a particular directory with samples)

SC: SCale
SD: SiDechain
SE: Sample Effect
SET: SETtings 
SEL: SELect
SG: Sample Group
SL: Sample Loop
SS: Sample Solo
SR: ShimmeRverb (not there yet but should be possible)
SRC: SouRCe
ST: STereo spread 
SQ: SeQuencer 

TE: Track Effect
TR: TRemolo
TG: TriGger 
TS: TranSpose

LE: LEngth
LF: LFo
LG: LeGato
LR: L/R paning
LS: Light Sensor
LT: LayouT
LV: LeVel 

V0: Voiceover Off
V1: Voiceover On

VC: VoiCe
VE: Voice Effect
VD: VocoDer (finally we got enough power to do this!)
VL: VoLume 
VR: VibRato

So you can enter a complete command using 2 letters from these pads and sometimes a parameter using bottom row of the pads, such as:

set a sample to loop forever: SL & 1
set a sample to not loop: SL & 0
set a sample to loop exactly N times: SL & 2...999

Sometimes, when the parameter for an effect is not numerical, you can use these pads to set it, such as:

change modulation on an effect to random: MD & R-D
change modulation on an effect to light sensor: MD & L-S
change modulation on an effect to accelerometer's x-axis: MD & A-C & X
change modulation on an effect to LFO #1: MD & L-F & 1

This is probably as complex as it gets, so the codes should be easy to memorize (and if you are lost, you can still invoke audible help)
