1. compatible with Arduino that we brought to exposed thru hole pads on the PCB Seven of them Please keep in mind that those are DIRECT connections to the microcontroller s pins so no protection are in place As a first and in presence of low voltages not exceeding 5V you can just use current limiting resistors 100 ohm in series with those inputs As a more robust stuff protect the input with diodes to 5V and GND Let s start with the already made connections By extracting some lines from the arduino sketch we know that Pins definitions analog define PITCH POT 2 define VOW POT 1 define CONS POT O define PITCH CV 3 define VOW CV 5 define CONS CV 4 Pins definitions digital define SOUNDGIN RES 2 define SOUNDGIN CTS e define GATE IN 10 define TX SW 9 TX_SW is clearly the serial line that gives commands to the soundgin babblebot chip To find informations and datasheets about this chip direct your browser here www babblebot net soundmachines user manual 5 RBirobotto Please refer to the firmware listing to find out what s going on and how to modifiy In the figure below you find indications where the unused microcontroller pins are and what are their name in the Arduino environment So you ve got two more analog channels and 5 digital I O pins That s pretty much very interesting Want to connect DACs Want to connect more pots You choose Enjoy the RB1robotto hacking2. and please let us know what you re doing Note altough this is extremely boring stuff all the cited trade marks and registered product names are property of their legal owners soundmachines user manual 6 RB1irobotto
3. botto engine is retriggerable as the minimum duration of the sound is very soundmachines user manual 3 RB1robotto small a little longer when used with consonants Gate input is standardized to 5V act Led this indicator is triggered by the generator chip soundgin and tells you when it s doing something i e generating speech sound noises It s useful also to understand if the module is correctly used and you actually should expect something at his output manual button this is a simple manual input direct to the gate input audio out jack this is a secret function We are not allowed to disclose it yet Hackers Only We decided to open the source code fo the robotto because many of its users would possibly desire to change its way of operating Considering that the sound source inside soundgin babblebot chip is quite powerful robotto could become something other from a complex monophonic synth voice maybe with an integral arpeggiator or generative stuff to a chord generator as the babblebot has six oscillators that could be used as simple voices just choosing the waveform and the ADSR Many other things could be and actually have been thought of so we encourage everyone to create their own robotto hack On the soundmachines site www sound machines it in the RB1robotto page there is the link to the firmware repository for you to play with or to restore robotto to its or
4. ding knob is set to ext The input range of the input is from O to 10V though the input is 12V tolerant The range is divided equally to the 5 main vowels aa e i or ue Vowel knob the knob is used to set the vowel and a couple of functions When the knob is set to ext the CV will determine the vowel that s been played When the knob is set to rnd random vowels will be chosen every time a gate transition willbe activated either manual or by means of external connections When the knob is in the active area a little more than EXT and a little less than RND the user simply changes the vowel by hand consonant input Same applies as the Vowel section just you know regarding consonants Also the input has the same range The consonant that we choose for the robotto are the following mapped from O0 to 10V se thh ko ch m j do Consonant knob if turned fully CCW in the OFF position no consonant will be applied to the sound Note that the consonant pronuciation takes time and it will delay the harmonic part of the sound so we decided to give you a way to disable this If turned fully CW to the RND sign the consonant will be randomized at each GATE trigger When the consonant knob is in the active range the consonant is determined either by the pot if the consonant CV is OV or the jack is not inserted or the CV input gate input this is the trigger for the robotto to sing Enough said The RB1ro
5. iginal firmware Contributors are welcome Here some basic information on the software and hardware of the board To allow you dear user hacker to work on the module without having to solder burn or harm anything anyone we put a very nice pin strip connector on top of the module pcb This connector is compatible among other with the version of the FTDI serial interface sold by Sparkfun www sparkfun com As of today the correct product number is DEV 09716 The interface will also give power to the module so you can test your stuff without having to put the module into the modular By having at hand this interface downloading the Arduino 1 0 environment from the Arduino website www arduino cc and starting some sort of creative mental process you can start coding and downloading stuff to the module soundmachines user manual 4 RB1robotto DISCLAIMER there is the remote possibility that you screw up the Arduino bootloader that we burnt on the board No big deal The board has a connector to reprogram the Atmel microcontroller By using another Arduino board or an even cheaper solution Atmel programmer made from some junk that you have lying in your drawers maybe you can easily restore the bootloader Please refer to the Arduino website for doing this it s very very well documented There are apart from the controls that you see on the panel several unused connection on the microcontroller that is
6. otected up to 5V and the others inputs up to 12V Current rating the module requires XXXmA on the 12V rail No current is drawed on the negative supply line Specifications Robotto module is a sound generating module Basic usage could be viewed as a very simple synth voice By using pitch cv and gate inputs the module will sing to the user s need Please refer to the following figure for input output jacks and control knobs soundmachines user manual 2 RBirobotto RB1robotto pitch input this input tracks the pitch of the voice outputting from the audio out jack of the module The useful amp input voltage is from O to 5V The tracking theoretically could be 5 octaves but speaking pun intended of voices it makes I D N much more sense to limit the tone to the three central D pitch octaves The pitch knob allow the user to tune or detune the robotto to the incoming voltage vowel XT E consonant amp OFF Pitch knob this knob serves as a fine tune knob It is mostly useful to adapt the tracking to the incoming voltage Center position detent should be good with correctly tuned act voltages vowel input this input jack permits the user to select the vowel of the voice The vowel could be changed also after the gate signal goes high thus permitting to change the vowel during the playing of a voice tone The vowel input is functional only when the correspon
7. soundmachines RBirobotto RB1irobotto User s Manual Introduction Care and feeding Specifications Hackers only chapter soundmachines user manual RBirobotto Introduction Robotto is a Voltage Controlled Voice a singing module a nice addition to any modular synthesizer Built around the Soundgin now Babblebot chip and an Arduino microcontroller Robotto is basically a controllable vocalizer The parameters that the user can modify through a CV Gate interface are the pitch the vowel and the consonant Not all the O 5V pitch interval is useful as the synthesizer core inside the Babbleboth is doing a good job around the central octaves Anyway if oddness is what you want feel free to explore Care and Feeding RBirobotto is an 8hp eurorack module designed to comply with the Doepfer power standard As the module has unipolar inputs and an AC coupled audio output we just need the 12V and GND 5V is generated internally Please use the supplied power cable The red conductor on the cable is connected to 12V supply rail as the standard implies On the PCB of RB1irobotto there is the clear indication of the polarity of the connector so please if you have a module without the connector inserted take care of the just orientation RB1robotto is protected against reverse insertion but you ll never know All the inputs are protected from over and undervoltages Specifically pitch and gate inputs are pr
