    I hope Ryouta considers making a 1:1 clone of TX81Z, that would let me sell my rack, lol.

    Please contact him about it! I would like to see him make a new VA or additive synth next.

    Do you have his email?

    I confirmed the difference between 12-bit and 24-bit by inserting a canal type earphone directly into the earphone jack of my iPadPro 10.5.
    My earphone grade is probably medium or somewhere between medium and low. Cable interchangeable. Not earphones for monitoring, but for listening.
    I used KQ Dixie as standalone, using the DYNO-MY preset in Default.dxpc in Factory Presets.
    (I’m speaking now under the assumption DYNO-MY preset exists in everyone's KQ Dixie.)

    • When using canal earphones, I noticed that in the low frequency range around the C1 to C2 range of the DYNO-MY preset virtual keyboard, the 12-bit has noise(?) on the sound output.
      I can't describe it well, but it sounds like there is a thin noise(?) as a background behind the preset sound. (This is a metaphor, and my explanation is not scientifically rigorous.)
      So I can say that the difference between 12-bit and 24-bit is quite clearly distinguishable in my case, depending on the situation.
      The difference is the presence or absence of noise. (There might be other distinct differences when using an external audio interface or DAC or headphones and speakers for monitoring.)

    • The sound from the speaker of the iPad itself sounded the same for 12bit and 24bit in my case. I could not tell the difference.

    • With the Ear-Pods with built-in microphone, probably made by Apple and bundled with an iPhone or something, I could hardly hear the difference (noise) between 12-bit and 24-bit unless I concentrated very hard.
      (So I think if the testers are not aware that they are now doing the A/B testing, they may not be able to distinguish the sound in this case.)

    (Incidentally, using that DYNO-MY preset, I could clearly hear the difference of filter on/off in the high frequency range with the speaker of the iPad itself in my case. And around the D5 virtual keyboard, it is quite audible. So the DYNO-MY preset may be versatile and useful for KQ Dixie users who want to check the sound difference of the setting functions.)

    +1, I actually dug out mine from the storage and no app comes close to emulating the roughness of the DA and quantisation noise and other aliasing quirks that make it what it is.

    The closest one we have is the Yamaha FM Essentials app that needs an unlock (local store no longer carries the MX line so I can’t unlock it on my new iPad).

  • is it possible to transfer presets from KQ DIXIE to volca FM 1st generation ?

    12bit covers a dynamic range of 72dB (which can be assumed valid in this case because the sound is synthesized, not sampled), so any difference results from signal levels lower than -72dB.
    The dynamic capabilities of a mobile device’s speaker are far below that range.

  • The 'charm' of 12-bit FM is the quantize noise that causes stepped modulation which can be further enhanced with WOTT especially on sounds using lower carrier output levels.

    I sampled the Latelybass from my TX81z and held the note until there was almost no audible signal left and it's quite easy to hear the quantization noise near the end of the sample especially at higher volumes...(Or using the MDR-7506's).
    https://www.dropbox.com/s/a6kgrzn050gxbug/LatelyBass5s.wav?dl=0

    Sampling the TX81z does no justice to it since every single note is calculated on the fly and the DAC is quite 'unpredictable'.
    (To cover the entire 'velocity range' we'd need 64+ samples for every single note to cover the parameter changes and that still would not cover the 'voice to voice' variation).

    So yeah, I'd be all in for a 1:1 emulation of the TX81Z and I have a unit on my desk to compare with so bring it on :sunglasses:

    Cheers!

  • Hadn’t bought it until now - what a great app! Downloaded some sysex files too (took me a while to figure out how to import them), and adding some chorus and reverb makes this sound fantastic.

    Plogue is developing a TX81Z emulation right now for desktop. However, they are focusing on the C64 SID and Famicom emulations.

    Plogue stuff is awesome. Looking forward to these. Definitely would love that TX81Z to be a reality. They'll nail it.

  • It’s gettin’ hard out there for an app.

  • if he would add SY77 / TX81z waveshapes..i'd tip him 10€!

    If he completely rejiggered the patch browser, made it more navigable and added a way to tag Favorites, I'd give him $10.

  • Since we're asking for features, I'd like to be able to drag the numbers directly in the main UI instead of having to go through submenus

  • The AUv3 seems to forget when I select the 12 bit option, maybe I’m overlooking something? Im hosting it on drambo

  • I can’t get any sound out of KQ Dixie. Got in open in AUM, connected the keyboard to it, and tried various sequencers but nothing…(?)
    Any clues?

    KQ Dixie works perfectly in AUM here. 11" M1 iPadPro, iPadOS17.5.1...

    Force shutdown and restart? That tends to fix a lot of problems.

    Dixie has had a lot of updates in the last month. Are you both on the same version of the app?

    Also, see this thread.

    My biggest complaint about KQ Dixie remains the preset picker. It remains the biggest weakness of the app and it would be fantastic if it was completely redesigned from the ground up (my preference is how Tal-U-No-LX has their preset picker designed).

    I’m always up to date before I reply :sunglasses:
    And no issues like mentioned in the other thread.

  • I can confirm that Dixie (v3.4.1) works flawlessly on my iPad Pro (iOS 17.5.1, M2) in AUM (v1.4.5), dRambo (v2.26), LP4i (v2.0), and standalone.

  • Looks like it’s still not working, but the dev is on it (another post on that thread!)

  • Thanks fo r your input folks. Have moved over to the KQD bug thread….

  • Is KQ Dixie a suitable synth for creating dark heavy DnB style basses? I’ve checked a few reviews and app introductions but they don’t seem to show if the app can create heavy patches.
    I would have thought with its FM synthesis it could be used in this manner.
    Also how does KQ rate versus Nambu?
    Or………..should I wait until Novembers Black Friday sale and purchase them both???
    Any help or suggestions are appreciated!
