https://www.electrosmash.com/mn3007-bucket-brigade-devices Helix buckets are dissapionting :( I happen to have EHX Memory Toy with BBD chips made by Behringer which is inferior to Memory Man. Comparision with Hx simulation is painful. Helix Buckets are dark and muffled. I do not understand why keep max delay time compatible with "originals" while sound is far from being "original" simulated.

Thank you! I see Motu interfacing and latency performance is just like my dream of Helix II. (Who knows, maybe AVB, Dante, AES67 are compatible already?) Still there are cheap USB2 interfaces on the market with similar RTL performance. I just hooked up my 2003 Digidesign Mbox 1. At 128 samples buffer @48kHz 20ms RTL - the same perfomance as Helix ASIO at the same settings. There are cheap SPDIF RCA to SPDIF optical converters on the market. AES/EBU (present in HxF, HxR, HxLT) can be easilly "converted" to SPDIF by using XLR to RCA cable with cold NOT CONNECTED to ground/shield. Always worked for me.

You can try, nothing dangerous should not happen. Mikes have very low voltage on low impedance, using unbalanced input you lose 6dB. The signal after AD conversion will be very low. This is why mic preamps were invented. Set guitar input to the lowest possible impedance, use one or two boosters - maybe you can push it to usable level. BTW - You can also try passive transformer Di box reversed.

It happens. Knowing how things work limits magical phenomenons. ;)

So aggregating on OSX is only possible for the same sampling rates. Am I right? Can you share the results of reported latencies (RTL) and what buffers are usable for your machine in the linked thread?

Can you demonstrate it somehow? Make a video when you twist Hx volume knob and yt video volume slider, daw master moving?

Helix native frequency is 48kHz. You can however download driver with higer latency to use other sampling rates. BTW It is described in the Owner's Manual page 58 (HxLT)

This is impossible. Helix Volume Knob is analog attenuator for a chosen Helix outputs. No way it can control anything on any other device than Helix. Using two interfaces at once can be confusing. Please consider to use one.

For me this is just the experience of rethorical sense of humour or open to any claim minded point of view :D

It's not an issue when you use ASIO4ALL. It is expected behavior described in A4A manual. Yes, I can use both ASIO DAW and multimedia sound with my two USB powered interfaces and Helix LT.

Will you pay me for that? Will you believe me I did it? Will you assume the test conditions are the same same as yours?

I think I can understand it. If this is the case sharing opinions on this topic makes no sense cause each case is diffrent, subjective, not measureable. Hovever scientific approach is about finding common ground, test, demonstrate, replicate the results and help someone with the knowledge collected this way.

Actually, the audiable difference is easy to check. You make a preset with hi gain amp model and place FX Loop DSP block in front, loopback it with patch cord and listen how much noise is added. Then you make a preset with 1/4" Out as send for the same Return, and listen. You can even compare instrument level with line level setting in both cases or Volume Knob influence. RMAA measured S/N ratio is about 110dBA in both cases.

Please do not believe in vocoder existence in Helix until somebody will prove that. This is the default rational position.

I am sorry but I can not confirm that. In fact when I measure noise performace, 1/4" Outs are 1dB noisier when Volume Knob is used. This is not audiable for me.

It does not matter what 1/4" inputs/outputs you use. They are almost identical. All outputs are TRS impedance balanced. That called "1/4" Output" can be controlled with Volume Knob. "Guitar Input" has variable impedance, pad and can not be set to "line level". Very same noise performance, same impedances, no difference.

HxN does not have anything ASIO related. It is just VST or AAX (Win) plugin. Reaper can use ASIO drivers. All of ASIO drivers I know have no limitations for ASIO clients number. ASIO4ALL is overlay for WDM driver. Its limitation is you can not use WDM driver for device it grabs for eg. multimedia sound. No point of ASIO4ALL usage unless you do not have (good) ASIO driver for your hardware or you want to aggregate devices. I do not know of any ASIO implementation for Spotify software. https://community.spotify.com/t5/Live-Ideas/Music-ASIO-Output-Support/idi-p/19519

Doesn't have a sound of it's own? With HF rolloff starting at 700Hz and 16% THD with drive about noon?

You are right. Now I can't understand why your "problem" remains after you sold the Helix.

This is what you claimed in your first post. Your "problem" was it does not work correctly. It does. No sign of forum users trying to solve your "problem" pointed to "not possible".

You will see. In case of stomps PSUs, the most important thing is how clean the power is, not the power.

I am not able to replicate your issue. Win10/Reaper5.96(64bit)/HxN1.71. All midi assigments are stored (I still prefer plugin automation) Maybe you take Reaper FX Presets for Helix Presets?

Presets are totally independent. Snaphots are not, but the idea of isolating chosen DSP blocks from snapshot bypass automation is really cool.

-6dB if we are talking of amplitude. Then -9dB when DI box has 3:1 transformer. 15dB gain on Helix Floor mic preamp should compensate this. Setting Return to "instrument" should deliver some gain (10dB?)

I thought compiling the kernel is just regular skill of every Ubuntu user.
