Questions about Cordial CFY 1.5 WPP - Y-adapter cable 3.5mm jack - 2x 6.3mm mono jack

If you are looking to record your keyboard through your Audio Interface, I would not buy this cable. You want to connect your 6,3mm Klinke output to the 6,3mm Klinke input. You can use a TRS cable, just make sure you set INST to "OFF" because that will work best with the TRS cable. The docs for the Scarlett say: "Input 2 uses a ¼” (6.35 mm) jack socket which is 2-pole when in instrument mode and 3-pole when used as a mono line input. It can accept signals from an electric or electroacoustic guitar or bass, a keyboard, and most other types of audio equipment. Set the INST switch ON (‘INST’ illuminates red) if you are connecting a musical instrument, e.g., a guitar in the example, using an ordinary 2-pole (TS) guitar jack. Set the INST switch to OFF if you are connecting a line level source such as a keyboard, synthesiser or the balanced output of an external audio mixer via a 3-pole (TRS) jack. Note the jack socket accepts both TRS and TS types of jack plug." https://fael-downloads-prod.focusrite.com/customer/prod/s3fs-public/downloads/Scarlett%20Solo%203rd%20Gen%20User%20Guide_EN.pdf page 13 This should be the exact cable that fits (there are other lengths too): Cordial CFM 1.5 VV (1.50m, Mid-range, 6.3mm jack) TRS means Tip Ring and Sleeve: 3 sections of the jack connector can be seen (like linked). Guitar cables are TS: Tip and Sleeve, only 2 sections are visible. You don't want Guitar cables.

We have some jack to 2x socket, otherwise at least none in mono. Depending on the installation, there may be an alternative. It is best to contact our customer service directly so that your question can be dealt with individually: https://helpcenter.digitec.ch/hc/de
