El Twisted Electrons hapiNES es un sintetizador compacto con secuenciador y sonido de Nintendo NES. El instrumento extremadamente manejable ofrece un secuenciador de cuatro pistas, que se reparten las cuatro voces. Dispone de un total de 60 sonidos de batería para acompañar melodías, líneas de bajo, blips y clicks de forma rítmica; el sonido número 60 es especial, pues cambia constantemente con cada nuevo accionamiento. Por supuesto, el auténtico bajo triangular y los osciladores rectangulares designados también están incorporados.
También presenta un arpeggiator de 16 patrones diferentes. La característica determinante es, sin duda, el chip RP2A07, conocido por ser el empleado en la popular consola de Nindendo NES. El Twisted Electrons hapiNes funciona con dos pilas AAA o mediante alimentación por Micro-USB. Además, la interfaz Micro-USB puede utilizarse independientemente de la conexión USB-MIDI.
If you're here you probably want to watch the creator's youtube tutorial first , it's really short and it showcases really well almost all the features this little machine has. Crispy triangle waves, noisy drums and hi-hats and arpeggiated PWM waves that will make you reminisce about the good ol' times of 8 bit consoles. Just google "Twisted-Electrons hapiNES Walkthrough" and give it a watch.
Sound 4/5: I have no complains about the sound quality itself, but the maximum volume is really low, and it can be tricky to get to hear things if you're in a noisy environment, Being a portable groovebox you might want to play with it in a bus, train or any other noisy place, but that can become a challenge due to the low volume.
Characteristics 5/5: You really have a lot of stuff to try with this, over 50 drum sounds including a random drum with customizable noise pitch and noise amount, arpeggiator, vibrato and PWM control over the square waves, transposing, key chaining and sequence chaining... nice! You have a few tempo settings but you can sync it with other gear, such as Pocket Operators, Korg Volca or your sync-capable MIDI controller. Talking about MIDI, It does have MIDI input, but only via USB-MIDI, and if you're not picky with the tempo you can use the input jack to mix your chip beats with external music.
Operation 4/5: My biggest issue is the amount of features packed in just a few buttons and knobs, with no other aid than the user manual (just a sheet) to remember (e.g. swing control, shortening sequences...) Personally I'd have preferred a little more silkscreen text in the board to help remember stuff, but it might have gotten a little cramped.
Craft(? Sorry the form is in my own language and I'm not sure how are the different ratings called in English) 5/5: You have a slightly thicker than usual printed Circuit Board in your hands with Hapines. most the circuit is hidden in the reverse side under a couple more PCBs, a good measure to avoid issues with sweaty hands, as someone who respects electricity I'm thankful about that. I tend to be really careful with PCB based synths but Hapines feels more sturdy than average, everything looks well in place and it's not gonna break anytime soon.
Price/performance 5/5: For a hundred euros this is a nice, cheap machine for NES and chiptune enthusiasts. I would call it a neat "toy" but the quality of sounds and the ability of control each track separately via midi makes it way better than what you'd expect from a toy.
PS: If you absolutely need a metal enclosure, better buttons or your usual MIDI-in, there's a new model of this synth coming out in March 2019 called hapiNES L.
PSS: I got a weird bug where some empty sequences had a drum beat in one of the 16 steps that couldn't be replaced by a rest, making the whole sequence silent, but it can be fixed entering live recording mode and pressing rest to delete the entire sequence. Weird.
