I can´t wait reading parts 2 and 3.
In “Making sense of the results” step 2 I try to plot waterfall or decay curves but the “generate” button doesn´t work. I mean, REW only generates a graph with the measurements curves, not the average curve.

Comment on How to stream TIDAL to the Raspberry Pi by John Thu, 10 Dec 2020 09:32:49 +0000 My setup is that I have connected my Raspberry Pi running PiCorePlayer with RCA to my speakers.
I bought iPeng for my iPhone and iPad.
Because I have a Tidal HiFi subscription, at least I can stream FLAC (I see that in my Logitech Media Server playback information). To make this happen, I have installed the Tidal Plugin for LMS.

My question, what is the advantage for me to add BubbleUpnp Server to my setup? iPeng is acting as a sort of Tidal Connect, right? I mean, iPeng is not sending a stream via BT to my Logitech MediaServer, but it streams the song directly from Tidal (as the RPi is a network streamer).

Second question, how can I make it happen that I can stream Master quality / MQA? Do I need a USB DAC for that? Or can I make it happen on the RPi somewhere?

Comment on How to stream Qobuz to almost anything by Mischa Fri, 23 Oct 2020 20:18:18 +0000 Thank you very much for this guide. Very useful.
I have it nor running with:
Qobuz Studio account
Linn Kazoo controller on Windows
Bubble UPNP server on a Linux machine (NAS)
Denon AVR-3600H amplifier/renderer (capable of 192 kHz – 24 bit)

It works flawlesly, but what ever i do, it never goes above 44 kHz – 24bit.

I don’t know, what i’m doing wrong…

Any ideas?

Comment on João Gilberto – White Album by yves seban Fri, 02 Oct 2020 23:15:12 +0000 If I may add this totally conjectural: I think that in Undiu, Gilberto seems to imitate the sound of berimbao, especially with the two hits on grave notes on guitar like a percussion.
huge fave of mine too. The album. Ma favorite song is Zingaro.

Comment on MOTU Microbook II by Tim Nelson Tue, 22 Sep 2020 02:17:25 +0000 I haven’t been able to use the MBIIc as a standalone mixer, either, but I’ve used the MBIIc with my iPhone as my personal mixer for keyboard and ambience mic inputs with separate outputs to keyboard amp (keys only) and my in-ear monitors (keys plus ambience). To control routing and mixing, I use my iPhone running AUM (Kymatica), connected to the Microbook via the (powered) Apple USB Camera Connector. AUM sees all inputs and outputs of the Microbook. Never had a disconnect, completely stable for me, as long as both MBIIc and iPhone are directly powered. You can add EQ, reverb and other effects in AUM with low latency. AUM has pretty much all of the mixing capabilities of CueMix FX with the MBIIc. It also has the advantage that it can record each stereo and/or mono input for you to mix later as multitrack at up to 96k, 32-bit floating point. Need to remember to turn off all other apps and transmitter/receivers on the iPhone (Airplane mode) at the gig!

Comment on How to Network your Mac music system with the Raspberry Pi and HiFiBerry – Part 3 by WILLIAM Mon, 31 Aug 2020 18:31:11 +0000 John,
Please let me know with I might be doing wrong. I am trying to use Lumin as my control app, it works (connect to both music sever and renderer, browses the library and plays music) but the Lumin app only allow control of volume. The timing ring, other controls in now playing section of the app are blank or not operable. I can select music and add it to the playlist and it plays in the correct order but the playlist display area and controls remain empty.
Any ideas what I am doing wrong are appreciated.
Lumin App 6.1.17 iOS
Volumio 2.806 Raspberry Pi 4 w/ HiFiBerry DAC+ Pro


Comment on MOTU Microbook II by Rob Aries Wed, 26 Aug 2020 01:42:31 +0000 I guess you can’t edit a post here; I wanted to fix a typo in my message above! But I also wanted to add a PS that this page (which is over seven years old as I type) is quite possibly the single clearest and most concise explanation of the MBIIc’s capabilities I’ve seen anywhere on the net. Kudos to John Reekie for putting it together – the block diagram by itself is gold! MOTU’s manual (actually *two* manuals) do a decent job, but there are several UI quirks in the CueMix FX app that can be confusing, especially with the myriad of mixing & routing options.

I’m a musician and originally used this interface with my midi keyboard and laptop music rig, playing virtual instruments. I set up a separate mix for the headphone output for my in-ear monitors; as John said, this box is unusal in that the headphone output is a separate stream, making this probably the only compact interface I could use. I got a mix from the monitor board through the XLR input and plugged a stereo electret condenser mic into the “line in 3-4” minijack – this for an ambience or “stage” mic. I then programmed my music software (Plogue Bidule) with the OSC commands to control the CueMix FX mixer, and linked those controls to knobs on my midi keyboard. This allowed me to control my in-ears mix as I played. I was so proud of myself for finally getting this to work; it was quite a bear getting OSC communication working! Then the MBIIc disconnects from my laptop in the middle of a show! Now I use my MacBook Pro’s stock headphone output and a standalone box (Rolls PM55P) to work my in-ears.

Anyway, sorry for this long post. I have to say that in August of 2020 I am not aware of any audio interface this compact that offers this many inputs & outputs, along with a built-in DSP mixer with EQ and dynamics. Maybe I’m wrong but I think this little guy is still one-of-a-kind. I hope my issues were just related to my OS version and I can go back to using it!

Comment on MOTU Microbook II by Rob Aries Wed, 26 Aug 2020 01:08:55 +0000 Vale, I haven’t visited this thread since my 2016 comment above! Just happened to come back to this page to refresh my understanding of the MBIIc’s routing scheme. I have not used it in several years due to it disconnecting in the middle of a gig (I’m a musician). Disconnection issues continued to happen as I tested it at home.

To answer your question, sorry to say but I have no new info regarding using the MBIIc standalone. My guess is the answer is still no. The latest driver I see for Mac is dated July 2017.

I’m cautiously testing my MBIIc to see if my issues were software-related or just a bum unit. I’m not sure I’ve tried using the inteface since I updated my MacOS from 10.11 (El Capitan) directly to 10.14 (Mojave).

If you can’t use the MBIIc standalone, maybe connecting it to an old iPod or iPhone would make a workable setup for you, since it’s class-compliant. You’d probably need to find an app that will patch the input through to an output.

Comment on Spatial Audio M3 Triode Master + interview with designer Clayton Shaw by Rich M Sun, 16 Aug 2020 03:44:28 +0000 I, too, own the Spatial M3 Triode Masters and after owning nearly 40 speakers over 40 years, these
are my favorites. I agree with the review above, that the sound is so clear and coherent that it
just allows the music to come thru. Low is bass is noticeably deficient compared to subwoofer
systems I have had in the past but the quality of bass is the best I have ever had.
I was surprised to hear that this model was not tested using flea powered amplifiers, but I can
state that my 15 watt EL84 integrated works just fine. I have a higher power tube integrated and I
suspect that these speakers can absorb a lot of current if needed. No need to hesitate with solid
state amps. Highly recommended.

Comment on MOTU Microbook II by Vale Mon, 20 Jul 2020 09:41:20 +0000 Hi Rob…
thanx for your caveat! I’ve got the same wish…would like to use it also as a standalone ADC to connect 2 external analog pres to another audio interface via spdif.
Any news? Is it possible now thanx to new drivers or yet impossible?
Thanx in advance,
