OpnBeat a DIY Open Source LoFi Sampler

https://www.hackster.io/hiro-akihabar... In this video I talk about OpnBeat which is an Arduino-based open source Lofi sampler. It uses a voice recorder chip, it is very simple so that you can modify it as you like. About OpnBeat: OpnBeat is Arduino-based Lofi sampler which is affordable, easy to understand and fun to play! Thanks to its core component the voice recorder chip ISD1700 series, OpnBeat is really simple. There is no complex technology such as mp3 or codec. The simplicity and understandability are useful for anyone who wants to modify it or make original DIY sampler. Most importantly, It's really fun to play. You need only a stereo audio cable, earphones and music source such as Sportify to start making your original track. The reason why they created this project: I love hip-hop music and become interested in sampler and music production. But popular samplers in market was expensive and since I've never tried making music before, I didn't have confidence whether I was able to use it or not. Finally I reached the idea that I should make it by myself so that I could fully understand how it works and how to use it. Main Features [Functions] Sampling sounds up to 12 second each for 8 channels(sampling frequency is about 12kHz, standard) Play 8 sounds at the same time Play mode (real time play by keys just like music instrument) Sound edit mode (cut and trim sampled sound) Rhythm edit mode (record and memory rhythm pattern by editing rhythm in realtime) BPM setting Level setting for each 8 channel output [Input / Output] 1x Line In (3.5mm stereo jack) 1x Line Out (RCA jack) 1x Headphone Out (3.5mm stereo jack) Volume (for heaphone, metronome) How it works Let me explain the core idea of the product. Its main component is voice recorder chip ISD1700 (in the prototype, ISD1720 is used). Usually it's used with standalone mode for simple voice recorder or toy applications. But OpnBeat uses it with SPI mode which enables full control of the chip. In sampling sound, sound signal is input from LINE IN stereo jack, then downmixed to monaural by U1 because ISD1700 inputs and outputs only monaural sound. The input audio signal is input to all ISD1700 chips in parallel. Arduino selects only one ISD1700 chip at once by SS (slave select). So the only selected ISD1700 chip executes record, play or change volume function depending on SPI command from Arduino. ISD1700 provides Direct Memory Access commands such as SET_PLAY or SET_REC which enable play and record sound segments based on designated memory address. Finally all the outputs from all ISD1700 chips are mixed by OPAMP (U1) and output from LINE OUT. Also the mixed signal is adjusted its volume and output from headphone out. The U2 is headphone amplifier. Just by specifying start and end address, you can trim and play recorded sound segment. It enables the device to trim and play only a shot of drum from seconds of recorded sound.
