Search for background applications and disable or terminate them while you are running your host. Background applications can be discovered by using the Activity Monitor (Mac) or Task Manager (Windows). These background applications also consume CPU and RAM. Your computer may also be running several “background” applications, such as disk backup utilities and anti-virus utilities. Terminate as many applications as you can, including browsers, email, etc. Each application consumes CPU power and RAM, and indirectly reduces the capabilities of the host. When using Keyscape, it is prudent to terminate all non-essential applications except your host application. Experiment with both to find the most efficient method. However, if your computer has multiple cores, using multiple instances with one sound each lets certain hosts (like Logic) spread the load over your computer’s cores, provided you have the available RAM. Consult your host’s reference guide for details. This is an advanced technique, and instructions vary from host to host. Load the various Patches into Omnisphere’s parts, and route the multiple MIDI tracks into the single Omnisphere instance using distinct Channels. If you have multiple MIDI tracks each with a dedicated instance of Omnisphere or Keyscape, it can sometimes be more efficient to instead use a single instance of Omnisphere in multitimbral mode. If you are using only a single Keyscape Patch and not employing any of Omnisphere’s advanced editing features, then using Keyscape as a standalone or a plug-in rather than loading it into Omnisphere will lighten the burden on the computer. In particular, Thinning may be required when using multiple large, sampled Patches within Omnisphere. All of the techniques described above apply to Omnisphere, and should be considered. The possibility of overloading the CPU or encountering streaming issues increases when using multiple Parts in Omnisphere. When loading Keyscape sounds into the Omnisphere instrument additional factors come into play because Omnisphere has eight Parts (multitimbral) and therefore permits a huge number of samples to be loaded. Offline bouncing typically yields better results for streamed samples, but realtime mode may also be satisfactory. If the host provides two bounce/freeze modes (offline and realtime), try them both. In Ableton Live use the menu File > Export Audio/Video. For example, Logic’s bounce feature is within the File > Bounce menu. Each host has a unique process for bouncing or freezing a track, so consult your host’s reference guide for details. If you need to edit the track after bouncing/freezing, hosts generally have an “unbounce” or “unfreeze” capability. Bouncing/freezing will convert the MIDI track containing Keyscape into an audio track ( WAV or AIFF). If you’ve finished arranging a track with Keyscape and are still encountering audio glitches, amother solution to consider is the host’s bounce/freeze capability. If using USB3, make sure the computer supports the USB3 interface. If you must place STEAM on an external drive, we recommend a fast connection such as Thunderbolt or USB3. In addition, it is strongly recommended that the STEAM data be placed on an internal drive, using an internal bus such as PCIe or SATA. The fastest drives are Solid State Drives ( SSD) which are preferred over HD disk drives which use a spinning platter. The performance of Keyscape depends on the speed of the drive on which the STEAM data is stored. Standalone use is highly recommended for live and studio situations. Using the Keyscape Standalone requires fewer of your computer’s resources than using it as a plug-in inside a DAW. The THINNING button can also be locked, ensuring that all Keyscape Patches load the thinned version automatically. The thinned versions of the Patches have been optimized to maintain the highest possible quality for each sound. This will reload the Patch with a reduced number of samples. If you encounter audio glitches, the first step is to use the THINNING button on the Settings Page. In some situations, you may need to perform several of these actions. The actions are listed in roughly the order you should consider them-starting with the easiest and highest payoff actions. You should consider all the methods listed, but note that some actions might not be appropriate for your circumstances. This section describes actions you can take to minimize these overloads. Additionally, some Patches use CPU-intensive FX units which might result in CPU overload, also causing audio glitches. If your system is not configured properly, streaming may not be fast enough and could produce audio glitches. The samples are streamed from your drive while you play. The models in Keyscape have been deeply multi-sampled and contain a large number of velocities and round robins.
