Description:

Buzz. Beep and bloop. We’re high on the lo-fi sounds of “old-school” games, toys and terminals and the Mainframe Bit Crusher takes us back in time to when Pac Man and Donkey Kong ruled the arcades, to when the Commodore 64 was high tech.

It provides sample rate reduction ranging from 48kHz to 110Hz. A little background… the sample rate is the number of times per second that a sample or snapshot of an analog signal is taken. For example, CDs (remember them?) had a sample rate of 44.1kHz which means that the original analog signal is sampled 44,100 times per second.

The sample rate defines the frequency range that can be reproduced while maintaining good fidelity. When the sample rate is reduced the quality of the audio is degraded and aliasing occurs. Aliasing means audible artifacts created when higher frequencies are sampled at an inadequate rate and the result is distortion. The Mainframe’s sample rate range is wide enough to take you from sounds that are quite pristine to sounds that are unrecognizable when compared to the input signal.

It also provides bit crushing ranging from 24-bit to 1-bit. What does that mean? Bit crushing is bit depth reduction. Back to our CD example… CDs used a 16-bit bit depth meaning that each of its samples was represented by 16-bits of information. Higher bit depths can accurately represent a greater dynamic range while bit crushing increases the number of sampling errors and creatively degrades the sound to bring us back to those nasty “old school” sounds we love.

The Mainframe’s selectable High/Low/Band-Pass filter lets the user shape the artifacts of the bit crushing and sample rate. Another very cool feature is its Sample Rate Tuning Mode where the pedal analyzes your input signal in real-time and sets the sample rate to match the pitch of your signal, or a set interval above your signal. This allows you to set the sample rate to match the key of a song, or it will continually adjust the sample rate based on what you play!

• Sample Rate Reduction ranging from 48kHz to 110Hz
• Bit Depth Reduction ranging from 24-bit to 1-bit
• Selectable High/Low/Band-Pass filter to shape the artifacts of the bit crushing and sample rate reduction

• Secondary knob parameters allow you to fine-tune the Mainframe’s effect.
• High quality buffered bypass and silent switching

    Fast-paced and fun
    Format: Kindle
    Kiyoshi Harai is 16 and a recent graduate of the exorcist academy. He’s insanely powerful, but the problem is, he’s terrified of demons, thanks to a childhood trauma. He also has social anxiety, which only shows on the inside. On the outside, he looks cool and glowering. The first volume follows Kiyoshi from his first assignment to his first exorcism post in the boons, which he chooses because of his hero who works there. He gets over his fear of demons pretty fast, thanks to a fatherly demon he needs to banish who gives him encouragement. At his post, he enrolls to a high school and gets to work on his other anxieties. This was a fun and fast-paced start to a series. Many demons were banished, but the line between good and bad people was blurry, and Kiyoshi made some unlikely friends too. Art was good. I’d read more.

    Loved it.
    Format: Paperback
    I’ve never read a Tezuka book I didn’t like and this was another masterpiece. Reminded me of George Orwell’s “Animal Farm”. Throughout the book I was trying to figure out how it was going to end. I had my theories, but the actual ending was perfect and it made me laugh.

    Another Tezuka scifi classic
    Format: Paperback
    The story is a collection of short, loosely connected, stories concerning birds. Attaining higher intelligence, they begin fighting back against humanity for dominance and freedom. The first few chapters are very reminiscent of Hitchcock's "The Birds" as they, seemingly out of nowhere, start attacking people and whole cities. Eventually there is a way to communicate and negotiate with them and a truce is made, however it doesn't end there. Many generations pass and birds start gaining larger brains, talking, wearing clothes, etc. And humans devolve into feral cavemen a la, "Planet of the Apes". It is worth noting that there is a chapter featuring a black character who is drawn in a outdated, racist, charicature style. As in all Tezuka books, there's a disclaimer about things like this given the time they were written. I believe, however, that it's worth mentioning as some people feel differently about things like that and with a disclaimer you can now decide for yourself if you want to make your own judgement of the work. That one part aside, I think the work is some of his best. His ideas and artistry really are top notch. You can also plan to lookout for more manga reviews from me Mangamatt, whether here or on other platforms.

    An under-appreciated Tezuka gem
    Format: Paperback
    Wonderfully strange book that toggles between absurd, hilarious, and poignant.

    I Welcome Our New Bird Overlords
    Format: Paperback
    A wild ride that's basically "What if Rise of the Planet of the Apes happened with birds?!" I love it when Tezuka is just... out there, too weird to look away.
