What the Strich Keyboard Range Is Built Around

The strich keyboard lineup is engineered around one consistent technical standard: full-size 88-key layouts with hammer-action weighted keys that replicate the mechanical response of an acoustic grand piano. Every model in the strich keyboards range uses graded weighting — heavier resistance in the lower register, lighter in the upper — which is the same physical characteristic that defines the playing feel of a traditional upright or concert grand. This is not a cosmetic feature. Graded hammer action directly affects how finger strength, articulation, and dynamic control develop during practice, which is why it is the central specification across the entire Strich product family.

The strich small keyboard format does not appear in this lineup. Every model here is full-size 88-key, which positions the range explicitly toward serious learners, intermediate players, and working pianists who require the full range of an acoustic instrument. The strich digital piano collection spans from portable stage-ready units to furniture-grade home instruments, but the key action standard remains consistent throughout.

SDP-P7 — Portable Hammer-Action Stage Piano

The strich piano model SDP-P7 is the most portable instrument in the current lineup, designed specifically for pianists who need to move between locations without sacrificing key action quality. The strich electric piano SDP-P7 features fully graded hammer-action keys with the same physical weighting profile found in the brand’s home console models. Sound sampling is drawn from European German-style grand pianos and processed through Strich’s multi-layer dynamic sampling technology with dual DSP processors, which eliminates the audio compression artifacts common in lower-specification digital instruments.

The 2-way speaker system on the SDP-P7 uses a configuration of 5W tweeters paired with 20W woofers per channel, producing a full-spectrum stereo output that separates high-frequency attack clarity from low-frequency resonance. This driver separation is relevant for pianists performing in small rooms or outdoor settings where a single-driver speaker would produce muddied mid-range reproduction. The strich weighted keyboard SDP-P7 supports dual wireless connectivity for MIDI transfer and audio streaming, and includes two headphone jacks for simultaneous silent practice — a practical feature for shared living or studio environments.

Sound Library and Practice Features

The SDP-P7 carries 200 tones and 60 demo songs. The dual keyboard mode, layer function, metronome, and transpose capability cover the standard practice and performance tools required for both self-directed learning and structured lesson work. The instrument bundles with sustain pedal, piano stickers, and music rest, making it a complete package for the player who wants to buy a portable performance-ready instrument without sourcing accessories separately.

SDP-120 — Home Console with Full Sound Library

The strich piano keyboard SDP-120 is positioned as a home practice and performance instrument with an expanded sound library relative to the portable models. It carries 200 tones, 700 rhythms, and 110 demo songs, with a maximum polyphony of 128 voices. The 2x15W built-in speaker configuration provides adequate volume for home room environments without requiring external amplification. The strich digital piano SDP-120 includes wireless MIDI connectivity alongside USB-MIDI, multiple audio ports, and a headphone output for silent practice sessions.

The SDP-120 includes a quality sustain pedal and a custom stand constructed from high-density board. The stand is not a generic third-party accessory — it is a purpose-built component matched to the instrument’s dimensions and finish. The black finish positions the SDP-120 as a piece of home furniture as well as a musical instrument, which is a relevant consideration for players who need the instrument to coexist visually with a living room or home studio environment. Those who want to order a strich piano stand as part of a complete home setup will find the SDP-120 bundle covers this requirement directly.

Interface and Connectivity

The LCD display and intuitive control layout on the SDP-120 make tone selection, rhythm programming, and function adjustments accessible without referencing the manual for routine operations. The wireless MIDI feature supports connection to iOS and Android applications for app-based learning platforms, composition software, and MIDI recording. USB-MIDI provides the same functionality for desktop DAW integration.

SDP-300S — Mahogany Furniture Piano with Wireless Connectivity

The strich piano SDP-300S introduces a wood-grain aesthetic specifically designed for integration with residential interior styles. The mahogany wood-grain finish is a custom specification applied by Strich, not a generic veneer, and the installation process is designed to result in a piece of music furniture rather than an instrument that visually conflicts with its surroundings. The SDP-300S carries 128 preset timbres, 200 drum rhythms, and 128-voice polyphony, with an audio-in port that allows external audio signals to play through the instrument’s own 25W speakers.

The strich digital pianos in the SDP-300S format include the full set of performance functions: chorus effects, layer, split, octave shift, and transpose. The intelligent auto chord function adds harmonic depth to single-hand melodic playing, which is particularly useful for students in the early stages of two-hand coordination development. The SDP-300S connects to teaching applications on iPad or smartphone via both wireless and USB-MIDI, supporting self-study, composition, and remote lesson formats.

Ivory Texture Keys and Grand Piano Feel

The 88 fully weighted and full-size keys on the SDP-300S carry a simulated ivory texture on the keytop surface. This texture replicates the grip and moisture-absorption properties of natural ivory without the material’s environmental and cost implications. For players transitioning from acoustic instruments, the key surface texture is as relevant to playing feel as the mechanical weighting underneath — both factors contribute to the tactile authenticity of the playing experience.

SDP-350S — Sliding Cover Piano with Triple Pedal and Expanded Timbres

The strich pianos model SDP-350S is the most fully specified instrument in the current lineup. It carries 900 preset timbres — the largest library in the range — alongside 700 drum rhythms, 128-voice polyphony, and the complete set of performance functions shared with the SDP-300S. The 25W x 2 speaker system provides room-filling output appropriate for home performance and teaching environments. A triple pedal unit is included, covering sustain, soft, and sostenuto functions — the complete pedal configuration of an acoustic grand piano.

The sliding key cover is a functional addition that distinguishes the SDP-350S from the other models in the range. When closed, the cover protects the keys from dust during periods of non-use and simultaneously transforms the instrument surface into a usable desktop or vanity surface. This dual-purpose design is particularly relevant for smaller living spaces where every horizontal surface serves multiple functions. The mahogany wood-textured finish places the SDP-350S in the same furniture-grade aesthetic category as the SDP-300S, making it compatible with farmhouse, industrial, and modern interior design contexts.

Premium Finish and Included Accessories

The SDP-350S ships with headphones, key stickers, the triple pedal unit, user manual, and power adapter. The headphones allow immediate silent practice without a separate purchase. The wood-textured finish with clean lines positions this instrument as the most visually refined option in the strich pianos lineup, suitable for placement in a main living area without visual compromise.

Technical Consistency Across the Strich Range

All four current models share the core technical standards that define the strich keyboard identity: 88 full-size keys, graded hammer-action weighting, wireless and USB-MIDI connectivity, and built-in speaker systems scaled to the instrument’s intended use context. The variation between models is in library size, speaker power, aesthetic finish, included accessories, and portability — not in the fundamental key action or connectivity standards.

This consistency means a player who develops technique on the entry-level portable SDP-P7 is working on a key action that transfers directly to the furniture-grade SDP-350S without adjustment. The graded weighting profile, key size, and surface texture are equivalent across the range. For teachers equipping multiple practice stations, or families purchasing a strich digital piano for a student who may later transition to performance instruments, this technical continuity is a practical asset.
