    MIDIbox SEQ/SID/FM : Wow.

    Message  Emmanuel le Mar 26 Jan 2010 - 2:02

    Amis du soir, bonsoir !

    Ca fait quelques temps que je n'ai pas écrit de post fourni ici, et il y a quelque chose qui me traîne dans la tête depuis quelques semaines. Ca va encore trotter longtemps avant de devenir un réel projet car, bien que ce soit assez peu fricophage, ça demande beaucoup de temps. Ben oui, c'est du quasi-DIY : on achète les composants, le circuit, le microchip, on fait faire la boîboîte, on soude, on déssoude (enfin, ça m'arrive...), on ressoude, on peaufine...

    Bref !

    Vous avez sûrement entendu parler de Ucapps ? Je ne vais pas m'étendre en longues conjectures sur l'histoire du nordique qui est à la base de tout ça, il y a juste quelques petites choses à savoir.

    1°) Midibox SEQ :

    SEQ, comme séquenceur. A la façon d'un doepfer MAQ 16/3 ou d'un Manikin Schrittmacher, à ceci près que c'est bien moins cher, plus joli selon vos goûts et que vous pouvez avoir la chance d'avoir un séquenceur unique.

    Qu'est-ce que la bête a dans le ventre ? Tout ça (pardon à ceux qui ne pratiquent pas l'anglais, mais vu la taille du pavé et l'heure, j'ai la flemme de traduire.) :

    Moi qui me mas***bait sur un Manikin croisé sur le net ya pas si longtemps...

    Côté look, ça peut donner ça :



    ... Ou ça :



    La première est vraiment sexy... Ce mec, Artesia, fait en général de très belles créations et doit, je pense, avoir quelques compétences non-négligeables en design industriel.

    2°) Midibox SID :


    "- SID... Aaaah, tu parles de ces sons de gameboy merdiques qu'on croise dans 80% des prods glitch-gameboy-8bit de mes deux ?
    - Mais oui !!!"

    ... Sauf que....



    C'est gras, rond, chaud... Je ne sais pas comment Thorsten Klose s'y prend, mais il fait de la bonne came.

    Et puis...


    it features four different software based synthesizer engine implementations:

    Lead Engine:

    Mono or Legato Play Mode, optional SusKey portamento/glide control
    8 modulation pathes with 24bit resolution. Each consists of two sources (e.g. ENV/LFO/MP Feedback/Wavetable/Constants), which can be combined with an operator (e.g. Add/Sub/Mul/XOR/AND/OR/Binary Operations/S&H/...) and routed to multiple modulation targets (e.g. Pitch/Pulsewidth/Filter/Volume/LFO Depth/Rate/Wavetable Position/CV outputs/...)
    Stereo modulation of two SID chips (=2*3 oscillators assigned to two audio channels), controlled from a single core
    2 DADDSRR envelopes sources with optional non-linear curve for Attack/Decay/Release. Positive/Negative (invertable) depth. Delayable. Different Loop Point configuration possible. Synchable to MIDI Clock. Retriggerable via Trigger Matrix.
    6 LFOs sources with different waveforms. Freerunning or synched. LFO Cross- and MIDI-Synchronisation possible via Trigger Matrix. Optional oneshot mode. Delayable. Selectable Phase. Positive/Negative (invertable) depth. Depth and Rate can be modulated via Modulation Matrix.
    6 independent Arpeggiators with various direction modes, variable octave range and gatelength. Optional oneshot mode and "constant cycle" time.
    4 independent Wavetable Sequencers with access to a 128 step memory, assignable to different sound parameters (also usable as sequencer for complex arpeggiator textures). Loop or Oneshot function. Wavetable position can be modulated from any source (e.g. Key Number, Velocity, ModWheel, Envelope, LFO, ...) via Modulation matrix. Step position can be incremented/reset via Trigger Matrix.
    Trigger matrix with various sources (e.g. Note/Envelope/LFO/MIDI Clock/...) and targets (e.g. OSC Gate/Envelope Attack and Release/LFO Restart/Wavetable Step and Restart/...)
    Fine Tuning and Pitch Bender with configurable Pitch Range
    Portamento/Glide function with different modes (logarithmic/constant time/Glissando)
    Oscillator Phase Synchronization with selectable delay between oscillators

    two independent basslines are available for left/right SID audio channel
    One master and two slave oscillators with different waveforms/octave transpose/sync/ringmod/static note/detune/variable phase offset!
    supports direct MIDI control or internal sequencing
    the basslines can be assigned to different MIDI channels and/or keyboard split zones
    2 independent Arpeggiators with various direction modes, variable octave range and gatelength
    8 sequences, directly controllable from MIDI keyboard or Control Surface
    Sequencer controls Note/Octave/Accent/Slide/assignable sound parameter
    external analog filters (e.g. Moog Ladder, SSM based, CEM based, original TB303 circuit, etc...) can be controlled from SW based envelopes and LFOs (-> F2A option)

    Drum Engine:

    optimized for C64ish drum sounds with dedicated parameter set (easy to use for fast success)
    16 drum instruments with dynamic or explicit voice allocation assignments
    20 different drum models with variable parameters (firmware allows to add more models in future)
    Supports direct MIDI control or internal sequencing
    8 sequences with 8 tracks, directly controllable from MIDI keyboard or Control Surface
    Thanks to the generic concept, each engine supports in addition:
    a consistent user interface
    "ensembles" which store the MIDI/Clock/Instrument configuration of 4 MBSID cores
    access to two SIDs per core
    each core can handle any synth engine (selectable via patch configuration)

    Modulation Wheel/Velocity/Aftertouch/PitchBender Assignments
    up to 256 parameters can be accessed via NRPN messages with full resolution
    access to all parameters and patches via SysEx
    non-destructive accesses to sound parameters (shadowed patches) from all control sources (e.g. Wavetable, Knobs, NRPN, CC, etc...)
    filter calibration for each connected SID (allows you to equalize both types, 6581 and 8580/6582)
    a random patch generator - not only for the whole patch, but also for individual parts

    3°) Midibox FM :

    D'après ce que j'ai pu lire, celle-là se construit à partir d'un chip Yamaha qu'on peut trouver en désossant des vieilles SoundBlaster Pro des 90's.

    C'est quoi alors ? Ben, un synthé FM... Et qui sonne !!!

    ---------------------------------------------------

    Bien sûr, il en existe d'autres, mais ce sont les 3 modèles qui ont vraiment retenu mon attention et qui me semblent le plus utiles/pertinents/relativement abordables pour un non-bricoleur/FAT !!!/Peu cher/mettezcequevousvoulezici.

    Ca va encore mettre de l'ordre, et surtout faire de la place dans mes priorités d'achat...

    Ah pardon, j'ai aussi oublié de parler d'un contrôleur midi. Et d'un autre, avec faders motorisés. Et d'une TR-808 like (vraiment "like", hein. A mon avis vaut mieux investir dans du software pour celle-là)... Et divers périphériques midi/CV/etc.

    Plus ça va, plus ça me les casse de me dire que je vais faire des études ---> Ca devait être le projet à la base, quand j'ai quitté mes groupes, etc et décidé de passer un équivalent de bac.

    L'année prochaine, je vais sans doute pointer à pôle-emploi, trouver une sorte de travail qui me permette de survivre, et un plein temps si j'ai de la chance. Je pourrai profiter de mon temps libre pour vraiment apprendre à coder sans culpabiliser de pas étudier la situation à Singapour où la "meth" chez les Blitzkrieg pendant la seconde guerre mondiale ; alors je me dis, pourquoi pas en plus me faire quelques petites bases en électronique ? J'y connais que dalle, ça fera un premier jet ; et vu comment ces bestioles sonnent... Je commence à douter de l'utilité d'un Virus chez moi... En fait, le seul VA qui garde de l'intérêt à mes yeux, c'est le Nord Modular. Parce que j'ai déjà eu un Nord Rack et que j'aime le son ; et parce que le côté modulaire est vraiment attirant.

    Bref, je digresse, je digresse ! J'ai presque hâte de pouvoir acheter les composants et de me prendre la tête pendant toutes mes nuits devant une table avec un fer à souder et une perceuse. En plus, si je veux des conseils, j'aurai qu'à me baisser, je connais quelques bricoleurs 'achement doués.

    Les midibox, vous connaissiez ? Connaissiez pas ? En projet ? Ou pas ?

    yop,

    moi je connaissais, d'ailleurs j'attends la version finale 4 du mbseq pour m'en faire une, j'ai également voulu me faire une sid à une époque mais j'ai un peu levé le pieds depuis

    bref ce site est génial et le matos qu'il construit le gars est carrément hallucinant Smile

    ps : une tite vidéo aussi sur le Seq que j'aimais bien : http://vimeo.com/2946305

    yep, de très belles passions qui trouvent ici de superbes réalisations, bon courage à vous deux

    je sais pour ma part que je n'ai définitivement pas le temps de développer quoi que ce soit dans ce domaine
