Q: On the particular device, whether iPhone or..?

Dear Armand,

1. I have a strong feel that you are looking at the wrong reasons.
A “slow” network should never result in a failure to connect or a failure to discover! If this is the case you are using the wrong tools or making really lousy code.

2. There is no information that IC Pro should require any special network. The stated requirements are:

_Recommended:

  • iPhone 4S, 5
  • iPad 2, 3, 4
  • iPad mini
  • iPod touch 5
    Cubase versions required:
    Cubase 6.5/7, Cubase Artist 6.5/7,
    Cubase LE/AI/Elements 6
  • Native 32-bit and 64-bit Cubase versions supported
    Important:
    The Steinberg SKI Remote extension has to be installed
    on the computer for Cubase iC Pro to work: Steinberg SKI Remote | Steinberg
    Cue mix functionality is only available together with Cubase 6.5/7._

3. Competitive products from the App store work without any problem on the same network.

Btw, enclosed are my Ping statistics when pinging the iPad from my Windows 8 installation.

Ping statistics for 192.168.1.71:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 35ms, Maximum = 117ms, Average = 75ms

This is the (worse/equal) Ping statistics when pinging from OS X (same machine, same network but with OS X and a working IC Pro)

Summary: I do not buy the BS about “Network latency”. The problem is as I see it the Steinberg implementation of the (for Windows) crappy Bonjour solution.
